You should see a cardiologist if you have symptoms that could point to a heart problem, such as chest pain or tightness, unexplained breathlessness, palpitations or an irregular heartbeat, dizziness or blackouts, or persistent swelling in the legs and ankles. You should also consider a check if you have significant risk factors even without symptoms, including high blood pressure, raised cholesterol, diabetes, or a family history of heart disease or sudden cardiac death. You do not need to wait for a dramatic event. In our experience, many of the most treatable heart conditions announce themselves quietly, through symptoms that are easy to brush off, and seeing a specialist early usually makes them far simpler to manage. There is one clear exception. If you have severe or crushing chest pain, sudden breathlessness, or other signs of a heart attack or stroke, you should call 999 rather than book an appointment, because a cardiology clinic is for assessment and planned care, not emergencies. The British Heart Foundation's guidance on heart attack symptoms sets out exactly what to look for. For everything short of that, a cardiologist is the right person to see when symptoms are new, recurrent, worsening, or simply unexplained, and when you would rather have a clear answer than live with uncertainty. Symptoms That Mean You Should See a Cardiologist Certain symptoms should always prompt a cardiology assessment, particularly if they are new, persistent, or getting worse. Chest pain or tightness. Discomfort, pressure, or tightness in the chest, especially when brought on by exertion and relieved by rest, can indicate angina or underlying coronary heart disease. The NHS guidance on chest pain explains when to seek help. Breathlessness. Shortness of breath that is out of proportion to your effort, or that comes on when lying flat, can be an early sign of heart failure or valve disease. Palpitations and irregular heartbeats. A racing, fluttering, or irregular heartbeat may point to atrial fibrillation or another arrhythmia. Even the common sensation of a skipped or missed beat is worth assessing if it happens often or comes with other symptoms. Dizziness, light-headedness, or blackouts. Fainting or near-fainting, particularly during exertion, always warrants a check. Swelling in the legs and ankles. Persistent, symmetrical swelling that does not settle overnight can be a sign of heart problems including heart failure, especially when it comes alongside breathlessness or fatigue. A heart murmur. If your GP hears a murmur, an echocardiogram can establish whether it reflects aortic valve disease, mitral valve disease, or something harmless. Risk Factors That Warrant a Check Even Without Symptoms Some people benefit from seeing a cardiologist not because of symptoms, but because their risk profile suggests it would be wise. This includes those with high blood pressure or raised cholesterol, people with diabetes, and anyone with a strong family history of heart disease, cardiomyopathy, or sudden cardiac death at a young age. From working with patients across South West London and the South-East over the past decade, we've found that a family history of sudden cardiac death in a close relative under 40 is one of the most under-acted-upon reasons to seek assessment. These are exactly the patients for whom early screening can be genuinely life-changing, yet they often assume that feeling well means there is nothing to check. A heart screening assessment is designed precisely for this situation. When It Is an Emergency, Not a Cardiology Appointment It is worth being completely clear on this distinction. Call 999 immediately if you or someone else experiences: Central chest pain that is severe, crushing, or lasts more than 15 minutes Chest pain with sweating, nausea, or breathlessness Pain spreading to the arm, jaw, neck, or back Sudden severe breathlessness Signs of a stroke, such as face drooping, arm weakness, or slurred speech These need emergency care, not an outpatient booking. A private or NHS cardiology clinic is the right route for planned assessment once any emergency has been excluded or ruled out. Do I Need a GP Referral First? Not necessarily. You can be referred by your GP, or you can refer yourself directly to a private cardiologist. If you plan to use private health insurance, check with your insurer first, as many policies require a GP referral before they will authorise a consultation. If you are self-funding, you can usually book directly without one. Either way, it is sensible to have a word with your GP about your symptoms, as they can often carry out initial checks and help point you in the right direction. What Seeing a Cardiologist Actually Involves A first appointment is rarely daunting. It begins with a detailed conversation about your symptoms, your medical history, and your family history, followed by a physical examination. From there, the cardiologist decides which tests, if any, are needed. Common first-line investigations include a 12-lead ECG to check the heart's rhythm and electrical activity, an echocardiogram to look at its structure and pump function, and blood tests through a diagnostic blood service. Depending on your symptoms, this might extend to an exercise tolerance test, ambulatory ECG monitoring, 24-hour blood pressure monitoring, or a CT coronary angiogram. The NHS overview of ECGs is a useful primer if you have not had one before. How We Approach New Patients at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we have completed in excess of 12,000 cardiac investigations, and our eight consultant cardiologists cover the full range of cardiac subspecialties. Because our physiologists carry out the tests in-house and our consultants report them under the same roof, much of the assessment can happen in a single visit through our diagnostic service, which keeps the time from first appointment to clear answer short. Two points from experience are worth sharing. First, in our experience, seeing a cardiologist early, while symptoms are still intermittent and mild, works better than waiting until they become constant, because the conditions we can influence most, such as early heart failure or the first episodes of atrial fibrillation, respond far better to treatment before they become established. Delay rarely makes a heart problem easier to treat. Second, we've found that a large proportion of patients who come to us worried about their heart leave reassured rather than diagnosed with serious disease, and that reassurance is itself a valuable outcome. Knowing that your symptoms are not dangerous is often exactly what allows you to get on with life, and it is one of the most common results of a thorough assessment. Conclusion You should see a cardiologist when you have symptoms that could be cardiac in origin, such as chest pain, breathlessness, palpitations, dizziness, or leg swelling, or when your risk factors and family history suggest a check is sensible, even in the absence of symptoms. The key is not to wait for a crisis. Early assessment gives you either a head start on a treatable condition or the reassurance that your heart is healthy, and both are worth having. Emergencies aside, which always need 999, a cardiologist is the right person to turn to whenever your heart raises a question you cannot answer. If you have symptoms or risk factors you would like assessed, you can contact Heartsure on 0208 255 5999, email info@heartsure.co.uk, get in touch through our contact page, or book an appointment online. Our team in Kingston-upon-Thames offers same-day appointments where clinically appropriate, and most patients are seen within the same week as their first enquiry.

A cardiac event recorder is a portable ECG device that records your heart's electrical activity around the time you experience symptoms, worn over an extended period so it can capture rhythm problems that come and go. Unlike a standard ECG, which takes a 10-second snapshot in clinic, or a continuous Holter monitor, which typically records everything for 24 hours to 7 days, an event recorder is built to catch infrequent episodes. It does this by saving a recording either when you press a button as you feel symptoms, or automatically when the device itself detects an abnormal rhythm. It is one of the most useful tools a cardiologist has for linking a symptom you can feel to what your heart is actually doing at that precise moment. If you have been offered one, or you are trying to understand why your symptoms keep getting "missed," here is the key point. The value of an event recorder is correlation. Many people with palpitations have a perfectly normal ECG in clinic, simply because nothing abnormal was happening during those few seconds. An event recorder solves that by monitoring over days or weeks and capturing the rhythm exactly when symptoms strike, so your cardiologist can either confirm that an arrhythmia is responsible or reassure you that your rhythm is normal during episodes. That answer is what actually guides treatment, which is why the device is so widely used. How a Cardiac Event Recorder Works The heart produces a small electrical signal with every beat, and an event recorder reads that signal through electrodes on the chest or through sensors on a handheld unit. What sets it apart from other monitors is memory and duration. Rather than storing a continuous recording, it holds a rolling loop of data and permanently saves only the segments that matter, either side of a symptom or an abnormal rhythm. Many looping recorders capture the period both before and after you activate them, which is important because the onset of an arrhythmia is often the most informative part, and by the time you have pressed the button the episode may already be underway. The NHS overview of ECGs explains how ambulatory recordings of this kind fit alongside the standard resting test. The Different Types of Event Recorder Patient-activated recorders. You trigger a recording when you feel symptoms, either by pressing a button on a worn device or by holding a handheld unit to your chest. Auto-triggered recorders. The device continuously analyses your rhythm and records automatically when it detects something abnormal, even if you feel nothing. This is valuable for arrhythmias that do not always produce symptoms. Looping memory recorders. Worn continuously with electrodes, these save the minute or so before and after activation, capturing the crucial onset of an episode. Implantable loop recorders. A very small device inserted just under the skin that can monitor for up to around three years. These are reserved for infrequent but significant symptoms, such as unexplained blackouts or an arrhythmia search after a stroke. How It Differs From a Standard ECG and a Holter Monitor The three tests answer different questions. A resting ECG is a brief, detailed snapshot, ideal for capturing the rhythm and conduction at a single moment but useless for a symptom that only appears twice a month. A Holter monitor records continuously over 24 hours to 7 days, which suits frequent daily symptoms. An event recorder trades continuous recording for a much longer monitoring window, which makes it the right choice when episodes are intermittent and unpredictable. In practice, the decision comes down to how often your symptoms occur. Daily symptoms are usually caught on a shorter continuous recording. Symptoms that appear every week or two, or less, generally need the longer reach of an event recorder to stand any realistic chance of being captured. What a Cardiac Event Recorder Can Detect An event recorder can identify a wide range of rhythm disturbances, including atrial fibrillation, supraventricular tachycardias and other forms of tachycardia, abnormally slow rhythms, pauses caused by heart block, and the ectopic beats behind the common sensation of a skipped or missed beat. Just as importantly, it can demonstrate a normal rhythm during symptoms, which is a genuinely useful and reassuring result that rules out a dangerous arrhythmia as the cause. The British Heart Foundation's overview of abnormal heart rhythms provides helpful background on the conditions these devices are used to find. When You Might Need One A cardiologist may recommend an event recorder if you experience: Palpitations that come and go and have not been captured on a standard ECG Unexplained dizziness or light-headedness Episodes of a racing, fluttering, or irregular heartbeat Blackouts or fainting with no clear cause Symptoms too infrequent to be caught within a 24-hour or 7-day recording The NHS guidance on heart palpitations is a sensible reference if you are trying to judge whether your symptoms warrant assessment. How We Use Ambulatory Monitoring at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we have completed in excess of 12,000 cardiac investigations, and rhythm-related symptoms are consistently among the most common reasons people come to us. Our ambulatory ECG monitoring provides wearable recordings of up to seven days, and the right type and duration of monitor is matched to how often your symptoms occur. Where longer-term or implantable monitoring is clinically indicated, the consultant advises on it and arranges it as part of your diagnostic pathway. Two things we have learned are worth passing on. First, we have found that roughly seven in ten patients we see for palpitations have a completely normal ECG at the moment of their clinic appointment, purely because the symptom was not occurring then. That single fact explains why extended monitoring, rather than a one-off trace, is so often the test that finally provides an answer. Second, on interpreting the results: in our experience, correlating the symptom you feel with the exact ECG trace recorded at that moment works better than simply detecting an arrhythmia in isolation, because a fast or irregular rhythm on the monitor only truly matters if it coincides with what you are experiencing. A brief run of an abnormal rhythm with no accompanying symptom, and a symptom with a completely normal rhythm, point in very different clinical directions. Rhythm monitoring is frequently paired with an echocardiogram to assess the heart's structure, which together give a far more complete picture than either test alone. What to Expect When Wearing One Wearing an event recorder is straightforward and unobtrusive. The electrodes are small and sit on the chest, the device itself is lightweight, and you carry on with normal daily life while it monitors. You will be asked to keep a brief symptom diary, noting the time and nature of any episode, because matching your written record to the recording is central to reaching a diagnosis. There is no pain, no radiation, and nothing invasive about a standard external recorder. Conclusion A cardiac event recorder is a portable, longer-term ECG monitor designed to catch the heart rhythm problems that briefer tests tend to miss. By recording around the time of symptoms, over days or weeks, it allows a cardiologist to confirm or rule out an arrhythmia and to link what you feel to what your heart is doing. For anyone whose palpitations, dizziness, or blackouts have so far gone unexplained, it is often the single most useful next step toward a clear answer. If you have symptoms you would like assessed, or you have been advised to have ambulatory ECG monitoring, you can contact Heartsure on 0208 255 5999, email info@heartsure.co.uk, get in touch through our contact page, or book an appointment online. Our team in Kingston-upon-Thames offers same-day appointments where clinically appropriate, and most patients are seen within the same week as their first enquiry.

The main reason people choose a private cardiologist over the NHS is speed of access, followed closely by continuity of care and the ability to choose the consultant they see. Where a routine NHS cardiology referral can involve a wait of several weeks to a few months, a private appointment can usually be arranged within days, often with the diagnostic tests completed in the same visit. For someone with symptoms such as chest discomfort, breathlessness, or palpitations, that difference in timing is the single thing most patients tell us matters to them. The NHS's own guidance on waiting times sets an 18-week standard from referral to the start of routine treatment, and while urgent and emergency care is rightly prioritised, non-urgent referrals frequently sit toward the longer end of that range. It is worth being clear from the outset, though, that this is rarely a question of one system being better than the other. The NHS provides world-class cardiac care, free at the point of use, and it remains the right route for emergencies and for many patients. Choosing a private cardiologist is not about better doctors; in our experience it is about faster access, longer appointments, and seeing the same specialist each time. In fact, many private cardiologists, including the whole consultant team at Heartsure, are practising NHS consultants. Going private often means seeing the very same senior specialist you might eventually see on the NHS, simply sooner and with more time. The NHS and Private Care Are Not an Either-Or Private cardiology works best when it is understood as a complement to the NHS rather than a replacement for it. You keep your NHS GP, you keep your NHS records, and you can move between the two systems as your needs change. Some patients use a private consultation to get a fast answer and reassurance, then continue any ongoing treatment on the NHS. Others use private diagnostics to shorten the path to an NHS procedure. The two systems are not in competition for your care; they can work together. One thing we always emphasise: if you are experiencing severe chest pain, sudden breathlessness, or symptoms of a heart attack, you should call 999 and go to A&E. Private outpatient cardiology is for assessment, diagnosis, and planned care, not for emergencies. The British Heart Foundation's guidance on heart attack symptoms explains when to seek emergency help. The Main Reasons Patients Choose a Private Cardiologist Speed of access. The most common reason by far. A prompt appointment means a prompt answer, which for anxious patients is often as valuable as the diagnosis itself. Choice of consultant. Privately, you can choose a cardiologist whose subspecialty matches your problem, whether that is heart rhythm disorders, valve disease, or cardiac imaging, rather than being allocated whoever is available. Continuity of care. You see the same consultant at each visit, who knows your history and follows your case through. In our experience, this continuity is one of the most underrated advantages of private care, particularly for conditions managed over months or years. Longer appointments. Private consultations are typically less time-pressured, which allows a fuller discussion of symptoms, options, and concerns. Diagnostics in one visit. Rather than being referred out for tests and waiting for separate appointments, much of the assessment can happen in a single attendance. A consultation, an ECG, and a scan such as an echocardiogram can often be completed the same day. You Often See the Same Consultants This point deserves its own heading because it is so often misunderstood. Private cardiology in the UK is largely delivered by consultants who also hold NHS posts. At Heartsure, all of our consultant cardiologists are practising NHS consultants who run our private clinics alongside their hospital work. The expertise is the same expertise; what changes is how quickly you can access it and how much time you get. This is why the honest framing of private care is not "better than the NHS" but "the same specialists, sooner." A patient worried about palpitations, an irregular rhythm such as atrial fibrillation, or possible angina is seen by a consultant of the same calibre they would encounter in an NHS clinic, without the wait. When Private Care Makes the Most Sense Private cardiology tends to be most worthwhile when timing matters. That includes situations where you have new or worrying symptoms and want a fast, clear answer; where a long wait would cause significant anxiety; where you need rapid testing for work reasons, such as a DVLA fitness-to-drive assessment; or where you value seeing one consistent specialist for an ongoing condition. It is also a sensible route for the reassurance of a thorough check when symptoms such as a heart that pounds or races at night are keeping you awake and you would rather not wait weeks to understand why. Equally, if your symptoms are stable, your GP is content to manage them, and you are comfortable waiting, the NHS route may serve you perfectly well. The right answer depends on your circumstances, not on a blanket rule. How Care Works at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we have completed in excess of 12,000 cardiac investigations, and our eight consultant cardiologists between them cover the full range of cardiac subspecialties. Because our physiologists perform the diagnostic tests in-house, and our consultants report them under the same roof, we can keep the whole pathway short. In our experience, seeing a consultant and completing the necessary diagnostics in a single visit works better than the conventional refer, wait, and return model, because it turns what can be a multi-week sequence of separate appointments into one afternoon, and the consultant can often give you an answer before you leave. We have found that the majority of patients who contact us are offered an appointment within a few days, and for straightforward cases many leave their first visit with a diagnosis already in hand rather than a further wait for results. Where more advanced imaging is needed, our working agreement with Kingston Hospital gives our patients access to tests such as a CT coronary angiogram through our diagnostic service. How to Arrange a Private Cardiology Appointment You can be referred by your GP, or you can refer yourself directly. If you plan to use private health insurance, check with your insurer first, as some policies require a GP referral before they will authorise a consultation; if you are self-funding, no referral is usually needed. Either way, our team can talk you through the options and guide you to the most suitable consultant for your symptoms. Conclusion Choosing a private cardiologist over the NHS is, for most people, a decision about access rather than quality. Private care offers faster appointments, continuity with a single consultant, more time in the room, and diagnostics completed in one visit, frequently delivered by the very same NHS consultants you might otherwise wait to see. It works alongside the NHS, not against it, and the NHS remains the right route for emergencies and for many patients. The best choice is the one that fits your symptoms, your circumstances, and how quickly you need an answer. If you would like to see a consultant cardiologist quickly, you can contact Heartsure on 0208 255 5999, email info@heartsure.co.uk, get in touch through our contact page, or book an appointment online. Our team in Kingston-upon-Thames offers same-day appointments where clinically appropriate, and most patients are seen within the same week as their first enquiry.

A DVLA medical test is a set of heart investigations used to confirm whether a cardiac condition affects your fitness to drive, and at Heartsure in Kingston-upon-Thames we provide these assessments for drivers across Surrey and the surrounding area. If the DVLA has written to you asking for a cardiac examination, it usually means you have a heart condition, or a suspected one, that falls under their medical standards, and they need objective evidence about how well your heart is working before they renew or reinstate your licence. The tests most commonly requested are a 12-lead ECG, an exercise tolerance test, and an echocardiogram or stress echocardiogram, all of which we carry out in-house. In practical terms, a DVLA medical test in Surrey does not have to mean a long wait or a trip into central London. You can arrange the required tests privately, complete them in a single visit where possible, and have the results reported by a consultant cardiologist and sent to the DVLA or back to you. This matters most for professional drivers, who are often unable to work until every result is in. The official DVLA guidance on cardiovascular disorders and fitness to drive sets out the standards in full, but the short version is that the tests are there to measure your heart's electrical activity, structure, and response to exertion, and to give the licensing authority the objective picture it needs. Why the DVLA Asks for a Cardiac Test You have a legal duty to tell the DVLA about certain heart conditions, and the GOV.UK guide to driving with a medical condition explains which ones. When you notify them, or when a condition comes to light another way, the DVLA refers to its medical standards and may ask for testing to decide one of three outcomes: that you can keep driving, that you must stop and tell them, or that you must stop for a set period until your heart is reassessed. The conditions that commonly trigger a request include coronary heart disease and angina, heart rhythm problems such as atrial fibrillation or heart block, valve disease including aortic valve disease, heart failure, and events such as a heart attack or the fitting of a pacemaker or defibrillator. In each case, the DVLA is not trying to stop you driving unnecessarily. It is applying a consistent safety threshold, and the tests exist to show whether you meet it. Group 1 and Group 2 Drivers, Why the Standard Differs The rules split drivers into two groups, and the distinction explains why some people are asked for far more thorough testing than others. Group 1 covers ordinary licences for cars and motorcycles. Group 2 covers lorries (LGV) and buses and coaches (PCV), and the medical standards here are considerably stricter because of the size of the vehicles and the hours spent at the wheel. A professional driver with the same condition as a private motorist will usually face a higher bar and more frequent reassessment. Taxi and private hire drivers, and those driving for Transport for London, often sit in this more demanding category too. From working with drivers across Surrey and South West London, we've found that professional drivers make up a large share of the DVLA assessments we carry out, and they are almost always the group under the most time pressure, because a lapsed medical can mean weeks off the road and lost income. The Tests a DVLA Medical Assessment Usually Involves 12-lead ECG. A simple, painless recording of the heart's electrical activity through electrodes placed on the chest. It looks at rhythm and conduction and is often the starting point. The NHS overview of ECGs explains what to expect. Exercise tolerance test. An ECG recorded while you walk on a treadmill or pedal a bike, so the heart can be assessed under physiological stress rather than at rest. This is frequently requested where coronary disease is the question, since some problems only appear when the heart is working hard. It is the same category of assessment that helps explain the kind of exertional chest tightness that can point to angina. Echocardiogram. An ultrasound scan of the heart's structure, valves, and pump function. The BHF's echocardiogram page describes how it works. Stress echocardiogram. A combination of the two above, imaging the heart before and immediately after exertion to look for structural changes under load. Our stress echo service is led by Dr Andrew Marshall, Consultant Cardiologist and specialist in cardiac imaging, and unlike some alternatives it uses no radiation. Where blood pressure forms part of the picture, 24-hour blood pressure monitoring can also be arranged. The rhythm-focused tests are also the ones that pick up the disturbances behind a heart that skips or misses beats, which is relevant for drivers being assessed for palpitations or arrhythmia. How We Handle DVLA Testing at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we've completed in excess of 12,000 cardiac investigations, and DVLA fitness-to-drive assessments are a steady and important part of that work. Because our physiologists perform the scans in-house and our consultants report them under the same roof, we can keep the pathway from appointment to reported result as short as possible. Two things we've learned are worth passing on. First, in our experience, completing all the DVLA-requested tests in a single visit works better than booking them piecemeal, because a professional driver is usually off the road until every result is in, and a fragmented schedule can add weeks of avoidable lost earnings. Where a driver needs an ECG, an exercise test, and an echo, we aim to sequence them into one attendance rather than three. Second, turnaround is what actually matters to most drivers, not the test itself. We've found that the large majority of professional drivers we assess are able to have their full set of results reported within a few working days of attending, which is the point at which they can move their licensing forward. For anyone whose livelihood depends on their licence, that speed is often the difference that counts. How to Arrange a DVLA Medical Test in Surrey You can be referred by your GP or another clinician, who can send a referral letter or complete our referral form, or you can refer yourself directly through our diagnostic service. If you are using private health insurance, check with your insurer first, as some policies require a GP referral; many drivers requiring DVLA testing choose to self-fund for speed. Bring the DVLA's letter with you if you have one, since it often specifies exactly which tests they want, and that lets us plan your visit precisely. Conclusion A DVLA medical test is simply a structured way of showing the licensing authority how your heart is performing, using a combination of ECG, exercise testing, and echocardiography chosen to match your condition and your licence group. Arranged privately in Surrey, it can be completed quickly, reported by a consultant cardiologist, and returned without the delays that keep professional drivers off the road longer than necessary. The tests are safe, mostly painless, and designed to get you a clear answer rather than to stand in your way. If you have been asked to arrange a DVLA medical test, or you want to organise your assessment locally, you can contact Heartsure on 0208 255 5999, email info@heartsure.co.uk, get in touch through our contact page, or book an appointment online. Our team in Kingston-upon-Thames supports both private motorists and professional drivers across Surrey, with most patients seen within the same week as their first enquiry.

An echocardiogram works by sending high-frequency sound waves into the chest and reading the echoes that bounce back. A handheld probe, pressed against the skin through a layer of gel, emits ultrasound pulses that travel through soft tissue and reflect off the boundaries between structures of differing density, such as heart muscle, valve leaflets, and the blood inside the chambers. The probe picks up those returning echoes, and a computer converts the timing and strength of each one into a live, moving image of your beating heart. Because sound also changes frequency when it bounces off something moving (the Doppler effect), the same scan measures the speed and direction of blood flowing through every valve and chamber. That is the mechanism. The experience is far simpler than the physics suggests. You lie on your left side, a physiologist applies gel and moves the probe across several positions on your chest, and the scan takes somewhere between 20 minutes and an hour depending on what is being assessed. It is painless, involves no radiation and no injection in its standard form, and you can eat, drink, and drive as normal straight afterwards. In our experience, what surprises patients most is the sheer volume of information a single non-invasive scan produces: chamber size, wall thickness, pump strength, valve structure, valve leaks, pressures inside the heart, and any fluid sitting around it, all from one appointment. What an Echocardiogram Actually Shows An echo answers structural and functional questions that an ECG cannot. The two tests are often confused, but they measure completely different things. An ECG records the heart's electrical activity, its rate and rhythm. An echo looks at the plumbing and the pump. The main outputs are: Ejection fraction. The percentage of blood the left ventricle pushes out with each beat, which is the headline number for pump function. The BHF's guide to reading an echo report explains what the figures mean. Valve function. Whether any of the four valves are narrowed (stenosis) or leaking (regurgitation), and how severely. Chamber dimensions and wall thickness. Enlargement or thickening points towards long-standing pressure problems such as hypertension, or towards a cardiomyopathy. Pressures. Doppler measurements estimate the pressure inside the heart and lungs without any invasive procedure. The pericardium. The sac around the heart, which can become inflamed or fill with fluid in pericarditis. What Happens During the Scan You remove clothing from the waist up and are given a gown. Small sticky electrodes go on the chest so we can track your rhythm alongside the images. The gel is cold and slightly sticky but harmless, and it simply removes the air gap between the probe and your skin, since ultrasound will not travel through air. The physiologist moves the probe to several standard windows: below the ribs, between them on the left side, and at the base of the neck. You may be asked to hold your breath briefly or roll further onto your side, both of which bring the heart closer to the chest wall and sharpen the picture. You will hear a swishing, whooshing sound at points, which is the Doppler signal picking up blood flow. Mild pressure from the probe is normal. Pain is not. The NHS overview of echocardiograms sets out the standard procedure. The Different Types of Echocardiogram Transthoracic echo (TTE). The standard scan, performed through the chest wall. This is what most people mean by an echo. Stress echo. Images taken before and immediately after the heart rate is raised, either on a treadmill or bike or with medication. Comparing the heart's wall motion at rest and under load helps identify coronary heart disease and reveals whether angina has a demonstrable basis. Contrast echo. A contrast agent is injected into a vein to brighten the border of the heart chambers when the standard images are unclear. Bubble echo. Saline containing microbubbles is injected to look for a hole between the heart's chambers, often after an unexplained stroke. Transoesophageal echo (TOE). A probe is passed down the oesophagus, which sits directly behind the heart, giving far sharper images of the valves and the left atrium. This one is mildly invasive and uses throat anaesthetic and sedation. The BHF's echocardiogram page covers each type in more depth. Why You Might Be Referred for an Echocardiogram The common reasons are: Breathlessness on exertion or when lying flat, particularly where heart failure is suspected A heart murmur heard by your GP, raising the question of aortic valve disease or mitral valve disease Swelling in the ankles and lower legs that does not settle overnight Chest pain or tightness, where structural causes need excluding Palpitations or newly diagnosed atrial fibrillation A family history of cardiomyopathy or inherited heart disease Monitoring an already known valve or muscle problem over time How We Approach Echocardiography at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we have completed in excess of 12,000 cardiac investigations, and echocardiography is comfortably our most requested scan. It is the workhorse of the diagnostic service, and it is performed in-house by our own cardiac physiologists rather than outsourced, which means images and consultant reporting stay under one roof. Two practical things we have learned are worth passing on. First, image quality is the single biggest limiting factor in echocardiography, far more than any weakness of the technology. Lung tissue, chest shape, and body habitus all affect how well sound reaches the heart. In our experience, roughly one scan in twenty needs a contrast agent to produce genuinely diagnostic images, and identifying that need during the appointment rather than recalling the patient later is what keeps the pathway short. Second, on test selection: in our experience, a stress echocardiogram works better than an exercise tolerance test alone for patients with suspected angina, because it shows the heart muscle's actual mechanical response to exertion rather than inferring it from electrical changes on a trace. We have found that around a quarter of patients with an equivocal treadmill result go on to a stress echo or CT coronary angiogram that resolves the question outright, sparing them a period of uncertainty that used to run into months. How to Prepare There is very little to do. Eat and drink normally, take your usual medication unless told otherwise, and wear a two-piece outfit so you only need to undress from the waist up. Avoid heavy moisturiser or body lotion on the chest that morning, since it interferes with the gel. Bring a list of your medications and any previous scan reports, because comparison over time is often more informative than a single snapshot. If you are booked for a stress echo, you may be asked to withhold certain heart rate medications beforehand, and we will tell you specifically if so. Conclusion An echocardiogram works by turning reflected sound waves into a moving picture of your heart, and Doppler measurements into a map of blood flow through it. It is safe, painless, radiation-free, and remarkably informative for a test that requires nothing more than gel and a probe. For anyone being investigated for breathlessness, a murmur, swelling, palpitations, or suspected valve or muscle disease, it is usually the single most useful scan available, and in most cases it delivers a clear answer within one appointment.

The sensation of your heart skipping a beat is almost always caused by an ectopic beat, an extra heartbeat that arrives slightly early and briefly disrupts your normal rhythm. What you actually feel as a "skip" is usually the short pause that follows the early beat, then the next beat landing harder than usual because the heart has had extra time to fill. Ectopic beats are extremely common, happen in almost everyone at some point, and in the vast majority of cases are completely harmless. Other causes of a skipping or irregular sensation include atrial fibrillation and other rhythm disturbances, which is why a symptom that recurs or comes with other signs is worth checking. If you've been searching because it keeps happening and you want to know whether it's serious, here's the short version. Occasional skipped beats, particularly when you're tired, stressed, or have had caffeine or alcohol, are normal and rarely need treatment. Skipped beats that come in frequent runs, that arrive with breathlessness, dizziness, chest discomfort, or fainting, or that occur against a background of known heart disease or a family history of sudden cardiac death, deserve a proper assessment. The company the symptom keeps matters far more than the skipped beat on its own. What a Skipped Beat Actually Is Your heart normally beats in a steady, coordinated rhythm driven by its own electrical system. An ectopic beat is triggered early by a small patch of heart tissue firing off ahead of schedule. There are two main types. Premature atrial contractions start in the upper chambers, and premature ventricular contractions start in the lower chambers. Both are common, and both usually feel the same to the person experiencing them. The odd thing is that people rarely feel the early beat itself. What registers is the compensatory pause afterwards and then the forceful beat that follows, which many describe as a thud, a flip, or the heart "turning over". The British Heart Foundation's information on ectopic beats explains the mechanism in more detail. The Most Common Triggers Ectopic beats are strongly influenced by lifestyle and circumstance. The usual triggers are: Caffeine. Coffee, tea, energy drinks, and even dark chocolate can provoke ectopics in sensitive people. Alcohol. A well-recognised trigger, particularly the morning after heavier drinking. Stress and anxiety. Raised adrenaline makes the heart's electrical system more excitable. The NHS guidance on anxiety covers the physical symptoms. Tiredness and poor sleep. Sleep deprivation lowers the threshold for ectopic beats. Nicotine. A stimulant that increases ectopic frequency. Dehydration and electrolyte imbalance. Low potassium or magnesium can make ectopics more frequent. Hormonal changes. Many women notice more skipped beats around their period, in pregnancy, or during perimenopause. An overactive thyroid. This raises the heart's excitability. The NHS information on an overactive thyroid outlines the wider symptoms. From working with patients across South West London and the South-East over the past decade, we've found that a large proportion of people who come in worried about skipped beats can trace the pattern to two or three specific triggers, most often caffeine and disrupted sleep. Around 80% of the skipped-beat presentations we assess turn out to be benign ectopic beats with no underlying structural problem, once we've done the appropriate checks. When a Skipped Beat Points to Something More The cardiac causes worth ruling out are less common but more important to catch. Atrial fibrillation. Atrial fibrillation produces an irregular, sometimes chaotic pulse rather than the occasional isolated skip, and it raises stroke risk if left untreated. Some patients first describe it as "skipping" before the irregularity becomes more constant. The NHS information on atrial fibrillation explains why it needs proper management. Other arrhythmias. Tachycardia and conduction problems such as heart block can produce irregular or dropped beats, and the palpitations they cause sometimes overlap with the skipping sensation. A high ectopic burden. Even when ectopics are benign in type, a very high frequency can occasionally strain the heart over time and needs monitoring. Structural heart disease. In patients with existing coronary heart disease or heart failure, frequent ectopics carry more significance and warrant closer attention. In our experience, the single most reassuring feature is whether the skipped beats disappear during exercise. Benign ectopics typically settle as the heart rate rises, whereas ectopics that become more frequent with exertion are the ones we look at more carefully. When to Seek Help Arrange a cardiology assessment if you experience: Frequent or persistent skipped beats rather than the occasional one Skipping that comes with chest pain, breathlessness, or dizziness Fainting or near-fainting alongside the sensation An irregular pulse that doesn't settle Known heart disease or a family history of arrhythmia or sudden cardiac death The NHS guidance on heart palpitations is a sensible starting point if you're trying to gauge urgency. Skipped beats accompanied by chest pain in particular should be assessed promptly, as chest discomfort has its own range of cardiac causes. How We Investigate Skipped Beats at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we've completed in excess of 12,000 cardiac investigations, and skipped beats are one of the most common reasons people self-refer. A first appointment combines a detailed history, a consultant assessment, and a 12-lead ECG. The NHS overview of ECGs explains how the test works for anyone who hasn't had one. Because a resting ECG only records around 10 seconds, and skipped beats are intermittent by nature, most patients need extended monitoring. We use a wearable ECG monitor recording for up to seven days, which captures the rhythm at the exact moment the symptom occurs. Where structural disease is a possibility, an echocardiogram assesses the heart's chambers and valves, and bloods through our diagnostic blood testing service check thyroid function and electrolytes. If a rhythm is provoked by exertion, an exercise tolerance test can reproduce it under controlled conditions. In our experience, quantifying the ectopic burden over a full week works better than a one-off recording because it tells us not simply whether ectopics are present, but what proportion of the total heartbeats they make up. That figure is what actually determines whether reassurance or treatment is the right answer, and we've found that most patients worried about skipped beats have a burden well under 1%, which is firmly in the benign range and often more reassuring to see written down than any verbal explanation. Practical Steps to Take Before Your Appointment A few simple things help us reach an answer faster. Keep a symptom diary for two weeks, noting the time of each episode, what you'd eaten or drunk, your caffeine and alcohol intake, and your sleep and stress levels. Track your heart rate on a smartwatch if you have one, since several modern devices now record a single-lead ECG trace that we can corroborate. Try cutting caffeine and alcohol for a fortnight, because if the skipping eases, you've already identified a trigger, and if it doesn't, that narrows the picture. Finally, note any family history of rhythm problems or sudden cardiac death, as this shifts our diagnostic priority. Conclusion A heart that skips a beat is, in the great majority of cases, experiencing harmless ectopic beats driven by caffeine, alcohol, stress, tiredness, or hormones. But because a small proportion of skipping sensations reflect atrial fibrillation or another rhythm problem, and because frequent ectopics occasionally matter in their own right, a persistent or worsening pattern deserves a proper assessment rather than guesswork. The right combination of consultation, ECG, extended rhythm monitoring, and where needed an echocardiogram gets most patients to a confident, and usually reassuring, answer quickly.

Leg swelling can point to several heart problems, with heart failure being by far the most common cardiac cause. When the heart can't pump efficiently, blood backs up in the veins and fluid is pushed out into the surrounding tissue, settling under gravity into the ankles, feet, and lower legs. Other cardiac causes include valve disease (especially right-sided problems), poorly controlled atrial fibrillation, pulmonary hypertension, and pericardial disease. That said, not every swollen ankle is a heart issue. In our experience, around half the patients we assess for leg swelling turn out to have a non-cardiac cause such as venous insufficiency or a medication side effect. The reason it still warrants checking is that the cardiac causes tend to be progressive, and they respond far better to treatment when caught early. If you've been searching because your legs or ankles have started swelling and you want to know what it means, here's the short version. Mild puffiness at the end of a long day on your feet, in hot weather, or after a long flight is usually harmless. Swelling that is already there when you wake, doesn't settle when you raise your legs, affects both legs roughly equally, or arrives alongside breathlessness, tiredness, or unexplained weight gain is the kind that points towards the heart and should be assessed. The pattern of the swelling tells us more than the swelling itself. Why Heart Problems Cause Leg Swelling When the heart is working well, blood returning from the legs flows easily back to the right side of the heart, through the lungs, and out around the body. When that pump weakens, or the right heart has to strain against high pressure, fluid leaks from the smallest blood vessels into the tissue, and gravity draws it down into the lower limbs. This is known as dependent oedema, and it has a recognisable signature. It is typically worst by evening, often eases overnight while you're lying flat, and leaves a dent when pressed firmly with a finger, which is called pitting oedema. The NHS guidance on swollen ankles, feet and legs sets out the wider picture. Heart Failure, The Main Cardiac Cause Heart failure is the leading cardiac reason for leg swelling. Right-sided heart failure causes the most visible lower-limb swelling, because the right ventricle struggles to move blood through the lungs and pressure backs up into the body's veins. Left-sided heart failure tends to flood the lungs first but eventually drives leg swelling too. It rarely shows up on its own. Most patients also notice breathlessness on exertion or when lying flat, unusual fatigue, weight gain of a kilogram or two over a few days as fluid builds, and sometimes a heart that feels like it's pounding once they're in bed as the body works harder to compensate. The British Heart Foundation's heart failure information covers the full presentation. From working with patients across South West London and the South-East over the past decade, we've found that roughly 60% of those who arrive with swelling in both legs plus any degree of breathlessness have at least early-stage heart failure once assessed. Identifying it at that point genuinely changes the treatment and the long-term outlook. Other Cardiac Causes of Leg Swelling Valve disease. Right-sided valve problems, particularly tricuspid regurgitation, raise pressure in the venous system and produce swelling. Severe left-sided disease such as aortic valve disease or mitral valve disease eventually pushes right-sided pressure up too. The BHF's heart valve disease page explains how a failing valve causes symptoms over time. Atrial fibrillation. Sustained, poorly controlled atrial fibrillation can lower cardiac output and lead to fluid retention, especially in older patients. The NHS information on atrial fibrillation outlines how it affects the heart's pumping. Pericardial disease. Pericarditis, particularly the constrictive form, stops the heart filling properly and congests the venous system. Swelling here often comes with chest discomfort that worsens on lying flat. Pulmonary hypertension. High pressure in the lung arteries forces the right ventricle to work against resistance, and over time it tires, causing swelling and breathlessness. Non-Cardiac Causes Worth Considering Plenty of leg swelling has nothing to do with the heart. Common culprits include venous insufficiency and varicose veins, lymphoedema, kidney disease, liver disease, medications such as calcium channel blockers and anti-inflammatories, pregnancy, and simply standing or sitting for long stretches. In our experience, the single most useful question is whether one leg is affected or both. One-sided swelling is far more often venous, lymphatic, or a clot. Swelling that is even on both sides is more likely to be cardiac, kidney-related, or drug-induced, and calls for a broader assessment. Sudden swelling in one leg with calf pain or warmth can signal a deep vein thrombosis, and the NHS guidance on DVT explains when that needs urgent attention. When to Seek Urgent Help Seek urgent assessment, or call 999, if leg swelling comes with: Sudden or severe breathlessness Chest pain or tightness Coughing up pink, frothy fluid Confusion or fainting Sudden one-sided swelling with calf pain or warmth A rapid jump in weight over a few days For swelling that is more gradual but persistent, a planned cardiology assessment within a week or two is the sensible route. How We Investigate Leg Swelling at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we've completed in excess of 12,000 cardiac investigations, and leg swelling is one of the more revealing reasons people are referred, because it frequently uncovers a condition nobody had spotted. A first appointment pairs a detailed history and consultant assessment with a 12-lead ECG and an echocardiogram to check pump function, the valves, and the right heart. Bloods through our diagnostic blood testing service cover BNP or NT-proBNP (a marker of heart strain), kidney and liver function, thyroid function, and a full blood count. Where blood pressure may be playing a part, a 24-hour blood pressure monitor gives a far truer reading than a single clinic measurement. In our experience, an echocardiogram paired with BNP testing works better than an echocardiogram alone for catching early heart failure, because BNP picks up ventricular strain before it shows as a structural change on the scan. We've found that around a quarter of patients with leg swelling and an apparently normal echocardiogram have a raised BNP indicating early heart failure with preserved ejection fraction, and those cases would slip through on imaging alone. Where we suspect reduced coronary blood flow, a CT coronary angiogram or myocardial perfusion scan gives a non-invasive answer. Practical Steps to Take Before Your Appointment A few simple things help us reach an answer faster. Weigh yourself each morning for a fortnight and note any sharp changes. A gain of more than 1.5 kg over three days is a meaningful sign of fluid retention. Photograph the swelling first thing and again last thing at night, since the contrast shows how gravity-driven it is. List every medication, including over-the-counter painkillers and supplements, because several common drugs cause swelling and ruling them out is often the first useful step. Finally, note any breathlessness on stairs or when lying flat, as that shifts our diagnostic priority. Conclusion Leg swelling has many possible causes, and the cardiac ones, including heart failure, valve disease, atrial fibrillation, and pericardial disease, are worth identifying early because they respond well to treatment within the right window. The pattern of the swelling, whether it affects one leg or both, when in the day it peaks, and what other symptoms travel with it are the strongest clues to whether the heart is involved. A proper assessment combining consultation, ECG, blood tests, and an echocardiogram gets most patients to a confident answer quickly. If you've noticed leg swelling and want to understand what might be behind it, you can contact Heartsure on 0208 255 5999, email info@heartsure.co.uk, get in touch through our contact page, or book an appointment online.

Feeling your heart pounding at night is usually caused by one of three things. Your nervous system is in a heightened state from stress, caffeine, alcohol, or poor sleep, your body is responding to a hormonal or metabolic trigger such as low blood sugar or perimenopause, or your heart rhythm itself is misbehaving. In most cases the cause is benign and resolves with lifestyle changes. But because lying still in a quiet room makes your heartbeat far more noticeable than during the day, persistent nocturnal palpitations can also be the first hint of an underlying cardiac issue, particularly an arrhythmia, that benefits from proper assessment. If you've been searching for an answer because it's keeping you awake or waking you up, the short version is this. An occasional thumping sensation after a stressful day, a late coffee, or a heavy meal is normal. Pounding that happens most nights, lasts more than a few minutes, comes with breathlessness, chest discomfort, or dizziness, or wakes you from sleep regularly is worth investigating. In our experience at Heartsure, around 70% of patients who come to us with night-time palpitations have a clear, treatable cause identified within their first appointment cycle, and the rest benefit from extended rhythm monitoring to catch what a single ECG cannot. Why Your Heart Feels More Noticeable at Night There's a simple physiological reason that palpitations often feel worse after dark. During the day, your attention is filled with movement, conversation, and external noise. At night, lying still in a quiet bedroom, your awareness narrows to your body. A heartbeat that has been the same all day suddenly becomes audible against the pillow or felt against the mattress. On top of this, your autonomic nervous system shifts at night. Parasympathetic activity rises during sleep, slowing your resting heart rate. Premature beats and brief pauses become more noticeable against a slower baseline rhythm, which is why many people feel "skipped beats" or strong thuds more vividly when trying to fall asleep. This doesn't mean nocturnal palpitations are always benign, but it explains why a sensation that would go unnoticed during the day can feel alarming at midnight. The Most Common Non-Cardiac Causes Caffeine and alcohol. Both stimulate the heart and disrupt sleep. Alcohol in particular causes a rebound rise in heart rate a few hours after drinking, which often coincides with the early hours of the morning. Stress and anxiety. Elevated cortisol and adrenaline raise heart rate and the force of each beat. The NHS guidance on anxiety covers the physical symptoms in detail. Low blood sugar. Going to bed having eaten little, or after intense evening exercise, can trigger an adrenaline release overnight that causes pounding and waking. The NHS information on hypoglycaemia explains the typical pattern. Hormonal changes. Perimenopause and menopause are well-recognised causes of palpitations, particularly at night when hot flushes and disrupted sleep amplify the sensation. Thyroid problems. An overactive thyroid raises resting heart rate and force of contraction. The NHS guidance on overactive thyroid outlines the symptom picture. Dehydration. Reduces blood volume, which the heart compensates for by beating harder and faster. Sleep apnoea. Repeated drops in oxygen during the night trigger sympathetic surges and can cause pounding, waking, and morning fatigue. This is one we see commonly through our Kingston Lung Clinic referrals. Medications. Decongestants, asthma inhalers, certain antidepressants, and thyroid replacement can all raise heart rate. When Heart Pounding at Night Points to a Cardiac Cause The cardiac causes of nocturnal palpitations are less common but more important to identify. Arrhythmias. Atrial fibrillation often presents at night for the first time because vagal tone is higher during sleep, which paradoxically triggers AF in some people. Patients describe an irregular, fluttering, or chaotic beat rather than a steady pound. Other rhythm disturbances include tachycardia, heart block, and ectopic beats. The British Heart Foundation's overview of abnormal heart rhythms is useful background reading. Palpitations from structural issues. Mitral valve disease and aortic valve disease can cause a strong, forceful beat that becomes noticeable at rest. Heart failure. Early heart failure can present with palpitations, breathlessness on lying flat, and waking at night gasping for air. The BHF's heart failure information covers the typical pattern. High blood pressure. Sustained hypertension can cause forceful contractions that become noticeable at night, particularly in patients whose blood pressure rises rather than falls during sleep. From working with patients across South West London and the South-East over the past decade, we've found that the symptom pattern matters far more than the symptom itself. A regular, forceful thud usually points to a non-cardiac trigger. An irregular, fluttering, or chaotic rhythm needs a closer look. Waking from sleep with a racing heart and a sense of breathlessness has a different significance again. In Our Experience, When to Seek a Cardiology Assessment Arrange a cardiology assessment if you experience: Palpitations that wake you from sleep regularly Pounding accompanied by chest pain, pressure, or tightness A heartbeat that feels irregular or chaotic rather than fast or strong Breathlessness or dizziness alongside the pounding A family history of arrhythmia, sudden cardiac death, or inherited heart conditions Palpitations that don't settle within a few minutes The NHS guidance on heart palpitations is a sensible starting point if you're trying to gauge urgency. How We Investigate Nocturnal Palpitations at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we've completed in excess of 12,000 cardiac investigations, and palpitations rank consistently in the top three reasons patients self-refer. A first appointment combines a detailed history, a consultant cardiology assessment, and a 12-lead ECG. The NHS overview of ECGs explains how the test works for patients who haven't had one before. A single ECG only captures a 10-second snapshot, which is why most patients with nocturnal symptoms need extended rhythm monitoring. We use a wearable ECG monitor for recordings of up to seven days, which captures the rhythm at the moment the symptom actually happens. Where structural disease is suspected, an echocardiogram assesses the heart's chambers and valves. For patients in whom hypertension might be driving the symptom, a 24-hour blood pressure monitor is particularly useful because it captures nocturnal readings that a clinic measurement cannot. Bloods through our diagnostic blood testing service cover thyroid function, electrolytes, and full blood count. In our experience, a seven-day wearable ECG works better than a 24-hour Holter monitor alone for nocturnal palpitations because the symptom often doesn't occur every night. We've found that around 40% of patients with nocturnal palpitations who had a normal 24-hour Holter recording showed a clinically significant rhythm disturbance when monitored over a full week, and those findings would have been missed on the shorter recording. Practical Steps to Take Before Your Appointment A few simple things help us get to an answer faster. Keep a symptom diary for two weeks. Note what time the pounding started, what you ate or drank that evening, your alcohol intake, your stress levels, and whether it woke you or stopped you falling asleep. Track your heart rate if you wear a smartwatch. The data isn't medical-grade, but a clear spike during the symptom is a useful clue, and several modern devices now flag irregular rhythms that we can corroborate. Cut caffeine after midday and limit alcohol for two weeks before your appointment. If the symptom improves, you've already learned something useful. If it doesn't, that narrows the diagnostic picture. Note any family history of heart rhythm problems, sudden cardiac death, or pacemakers. This shifts our diagnostic priority. Conclusion A pounding heart at night is most often a benign response to caffeine, alcohol, stress, hormonal change, or simply lying still in a quiet room. But because cardiac causes such as atrial fibrillation, valve disease, and early heart failure can present this way, persistent or worsening nocturnal palpitations deserve a proper assessment rather than guesswork. The right combination of consultation, ECG, extended rhythm monitoring, and where needed echocardiography gets most patients to a confident answer quickly. If you've been feeling your heart pounding at night and want to understand why, you can contact Heartsure on 0208 255 5999, email info@heartsure.co.uk, get in touch through our contact page, or book an appointment online.

Chest pain can indicate a range of heart problems, from temporary reduced blood flow to the heart muscle (angina) through to a heart attack, inflammation of the heart muscle or its surrounding sac (myocarditis or pericarditis), valve disease, and abnormal heart rhythms. Not every episode of chest pain is cardiac in origin, and in our experience around half of the patients we assess for chest pain turn out to have a non-cardiac cause. But because the conditions that are cardiac can be serious, any new, unexplained, or worsening chest pain warrants proper investigation rather than guesswork. If you've been searching because you've experienced chest pain and want to understand what it might mean, the short answer is this. Pain that comes on with exertion and eases with rest most often points to angina. Pain that is sudden, severe, and accompanied by sweating, breathlessness, or pain spreading to the arm or jaw needs emergency assessment for a possible heart attack. Sharp, stabbing pain that worsens when you breathe in or lie flat usually points to pericarditis. The character, timing, and triggers of chest pain are the strongest clues to the underlying cause, which is why a detailed history matters as much as the tests we run. Angina, The Most Common Cardiac Cause of Chest Pain Angina is the textbook cardiac chest pain and the one we see most often. It happens when the coronary arteries supplying blood to the heart muscle become narrowed, usually by atherosclerosis, and can't deliver enough oxygen during exertion or stress. Typical angina has three hallmarks: it is a tight, heavy, or pressure-like sensation across the central chest, it is brought on by exertion or emotional stress, and it is relieved within a few minutes by rest or by GTN spray. The pain can radiate to the left arm, jaw, neck, or upper back. The NHS information on angina covers the symptom picture in more detail. In our experience, patients who describe predictable chest pain that comes on at a similar level of exertion each time almost always have stable angina, while those whose pain comes on at rest or wakes them at night need urgent assessment for unstable angina or impending heart attack. Heart Attack (Myocardial Infarction) A heart attack happens when blood flow to part of the heart muscle is suddenly cut off, usually by a clot forming on a ruptured plaque inside a coronary artery. Without oxygen, the muscle starts to die within minutes. Heart attack pain is typically more severe and prolonged than angina, lasting more than 15 minutes, and is not relieved by rest. It is often accompanied by sweating, nausea, breathlessness, a feeling of impending doom, and pain radiating into the arm, jaw, or back. The British Heart Foundation's information on heart attack symptoms is essential reading. If you or someone with you is experiencing these symptoms, call 999 immediately. Time is muscle in a heart attack, and outcomes are dramatically better the sooner treatment begins. Pericarditis and Myocarditis Pericarditis is inflammation of the thin sac surrounding the heart. The pain is usually sharp, central or left-sided, worse on deep breathing or lying flat, and often relieved by sitting forward. It commonly follows a viral illness and tends to affect younger adults more than other cardiac chest pain. Myocarditis is inflammation of the heart muscle itself. The pain pattern overlaps with pericarditis but is more often accompanied by breathlessness, fatigue, and palpitations. Both conditions need careful assessment because they can cause heart rhythm problems or affect pump function if not properly managed. We assess both conditions with a 12-lead ECG, an echocardiogram, and blood tests through our diagnostic blood testing service checking inflammatory markers and cardiac enzymes. Valve Disease Aortic valve disease, particularly aortic stenosis, can cause chest pain that mimics angina because a narrowed valve restricts how much blood the heart can pump out. The classic triad of aortic stenosis is chest pain, breathlessness, and fainting on exertion. Mitral valve disease can also cause atypical chest discomfort, particularly when accompanied by atrial fibrillation. An echocardiogram is the definitive test for valve disease. The NHS information on heart valve problems outlines what to expect. Arrhythmias Some abnormal heart rhythms produce chest discomfort, particularly when the rate is very fast. Tachycardia and episodes of atrial fibrillation can present with chest tightness, palpitations, and shortness of breath. The pain in these cases is usually a secondary feature, with the underlying rhythm disturbance being the main problem to identify and treat. Where rhythm-related chest pain is suspected, an extended ECG recording through our wearable ECG service is more useful than a one-off resting trace, because it captures the rhythm at the moment the symptom actually happens. Non-Cardiac Causes Worth Considering Not every chest pain is cardiac. Common non-cardiac causes include acid reflux, musculoskeletal pain from the chest wall or ribs, anxiety and panic attacks, lung conditions, and oesophageal spasm. The NHS guidance on chest pain helps put these in context. From working with patients across South West London and the South-East over more than a decade, we've found that the most useful single distinction is whether the pain changes with exertion. Cardiac chest pain almost always has a relationship with effort. Pain that is reproducible by pressing on the chest wall, that comes on after meals, or that varies sharply with mood and posture is more often non-cardiac. How We Investigate Chest Pain at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we've completed in excess of 12,000 cardiac investigations, and chest pain is consistently in the top three reasons patients self-refer. A first appointment usually combines a consultant cardiology assessment with a 12-lead ECG, bloods, and an echocardiogram where structural disease is suspected. For patients whose symptoms are clearly exertion-related, the next step is either a functional test using our exercise tolerance test or direct imaging of the coronary arteries with a CT coronary angiogram. Where blood flow to the heart muscle is the question, a myocardial perfusion scan gives a non-invasive answer. In our experience, a CT coronary angiogram works better than a treadmill test alone for patients with intermediate-risk chest pain because it shows the actual state of the arteries rather than inferring it from the heart's electrical response. We've found that around 35% of patients we send for CT coronary angiography after an inconclusive treadmill test have findings that change their treatment, most often a previously unrecognised plaque or moderate stenosis that needs medical management. When to Seek Emergency Care Call 999 immediately if chest pain is: Sudden, severe, or crushing Accompanied by sweating, nausea, or breathlessness Spreading to the arm, jaw, neck, or back Lasting more than 15 minutes and not relieved by rest Associated with collapse or near-collapse Do not drive yourself. Chew an aspirin (300 mg) if available and you are not allergic, and wait for the ambulance. Conclusion Chest pain has many possible causes, and the cardiac ones include angina, heart attack, pericarditis, myocarditis, valve disease, and arrhythmias. The character, timing, and triggers of the pain are the strongest clues to which condition is responsible, and a proper cardiology assessment combining consultation, ECG, bloods, echocardiogram, and where indicated coronary imaging gets most patients to a confident answer quickly. The risk of leaving cardiac chest pain unexamined is far higher than the inconvenience of getting it checked.

Our team in Kingston-upon-Thames offers same-day appointments where clinically appropriate, and most patients are seen within the same week as their first enquiry.

Peripheral arterial disease (PAD) is a circulatory condition where the arteries supplying blood to your legs, and sometimes arms, become narrowed or blocked by a build-up of fatty deposits called plaque. This restricts blood flow to the muscles, most commonly causing cramping or aching pain in the calves, thighs, or buttocks when walking, which eases with rest. PAD is a form of cardiovascular disease and shares the same underlying process as coronary heart disease, which is why having PAD significantly raises the risk of heart attack and stroke. The condition is more common than most people realise. The British Heart Foundation estimates that around one in five people over 60 in the UK have some degree of PAD, although many don't know it because early symptoms can be mild or mistaken for general ageing. In our experience at Heartsure, the patients who come to us with PAD are usually in one of two camps. Either they've started noticing leg discomfort when walking and want to understand what's causing it, or they've been told by their GP that their pulses are weak and need a proper vascular assessment. Both groups benefit from early diagnosis because the disease responds well to treatment when caught before it progresses. What Causes Peripheral Arterial Disease PAD is caused by atherosclerosis, the gradual build-up of fatty plaques inside the artery walls. The same process drives coronary artery disease, which is why patients with PAD almost always have a degree of disease in their heart arteries as well, even if it hasn't yet caused symptoms. The main risk factors are: Smoking. This is the single biggest modifiable risk factor. Smokers are up to four times more likely to develop PAD. Diabetes. High blood sugar damages arterial walls over time and accelerates plaque formation. High blood pressure. Sustained hypertension stiffens and damages the arteries. High cholesterol. Elevated LDL cholesterol is the primary fuel for plaque formation. Age. Risk rises sharply after 60. Family history. A close relative with cardiovascular disease raises your baseline risk. Sedentary lifestyle and obesity. Both contribute to the wider cluster of cardiovascular risk. From working with patients across South West London and the South-East over the past decade, we've found that PAD rarely exists in isolation. Around 70% of the patients we diagnose with PAD also have at least one other significant cardiovascular risk factor that needs managing, and roughly half have undiagnosed high cholesterol or borderline hypertension picked up on the same visit. The Symptoms of Peripheral Arterial Disease The hallmark symptom is intermittent claudication, which is medical shorthand for cramping or aching pain in the leg muscles brought on by walking and relieved by rest. The pain usually appears in the calf but can affect the thigh or buttock depending on which artery is narrowed. Other signs to watch for include: A cold feeling in one foot or leg compared to the other Slow-healing wounds on the feet or toes Numbness or weakness in the legs Hair loss on the legs or feet Toenails that grow more slowly or look brittle Pale or bluish skin on the lower legs A weak or absent pulse in the feet Pain in the feet or toes at rest, particularly at night The NHS guidance on peripheral arterial disease covers the full symptom picture in more detail. Importantly, around a quarter of people with PAD have no symptoms at all, which is why screening matters in higher-risk patients. How Peripheral Arterial Disease Is Diagnosed Diagnosis combines a clinical assessment with non-invasive testing. At a first consultation, we take a detailed history, examine the legs, feel for pulses at the groin, behind the knee, and on the foot, and listen for turbulent flow over the arteries with a stethoscope. The most important bedside test is the ankle-brachial pressure index (ABPI), which compares the blood pressure at your ankle to that at your arm. A normal ABPI sits between 0.9 and 1.3. Lower readings indicate progressively more severe narrowing. We measure this routinely as part of a vascular assessment using our 24-hour blood pressure monitoring service infrastructure adapted for ankle readings where indicated. Where the picture warrants further investigation, the next step is usually imaging. A duplex ultrasound shows the arteries in real time and is the standard first-line scan. For patients in whom we suspect coexisting coronary disease, which is common, we often combine the vascular workup with a cardiac assessment. This typically includes a 12-lead ECG, an echocardiogram to check heart structure and function, and bloods through our diagnostic blood testing service covering cholesterol, glucose, kidney function, and inflammatory markers. In our experience, combining vascular and cardiac assessment in the same visit works better than treating PAD in isolation because nearly every patient we see with confirmed PAD has at least subclinical coronary disease that benefits from earlier detection. We've found that more than 60% of PAD patients we assess at Heartsure have additional cardiac findings that change their treatment plan, whether that's tighter blood pressure control, a statin adjustment, or further coronary imaging through a CT coronary angiogram. How Peripheral Arterial Disease Is Treated Treatment has three goals: relieve symptoms, slow disease progression, and reduce the risk of heart attack and stroke. The approach is layered. Lifestyle changes sit at the foundation. Stopping smoking is the single most effective intervention. Structured walking exercise, ideally to the point of mild discomfort and then resting before continuing, genuinely improves walking distance over weeks to months by encouraging the body to grow collateral blood vessels. Weight management and a Mediterranean-style diet support both vascular and cardiac health. Medication typically includes a statin to lower cholesterol regardless of baseline levels, an antiplatelet such as clopidogrel or aspirin to reduce clot risk, and tight control of blood pressure and diabetes where present. The BHF's overview of cholesterol-lowering medication explains how statins work in this context. Procedural treatment is reserved for patients whose symptoms significantly limit their quality of life or whose disease threatens limb viability. Options include angioplasty with or without stenting, and in some cases surgical bypass. These decisions are made jointly with vascular surgeons, and at Heartsure we coordinate referral through our network where appropriate. When to See a Cardiologist About PAD You should arrange a cardiology or vascular assessment if you experience: Cramping or aching leg pain when walking, particularly if predictable at a similar distance each time Cold or discoloured feet A non-healing wound on the foot or lower leg Known cardiovascular risk factors (diabetes, smoking history, family history) and any of the above A weak or absent pulse in the feet noted by your GP Rest pain in the feet, particularly at night, or any sudden change in the colour, temperature, or appearance of a foot needs urgent assessment. These can indicate critical limb ischaemia, which is a medical emergency. What Living With PAD Looks Like PAD is a chronic condition, but it's a manageable one. Most patients diagnosed in the early or moderate stages live full, active lives once their risk factors are properly controlled and they've built walking back into their routine. The patients who do best in our follow-up clinics tend to share three habits: they stop smoking permanently rather than cutting down, they walk daily even when it's uncomfortable, and they attend their annual cardiovascular review without skipping. The BHF's living with PAD guidance is a useful resource for day-to-day management. Conclusion Peripheral arterial disease is a common but under-recognised condition that signals wider cardiovascular risk. The leg symptoms it causes are usually what brings patients in, but the more important issue is what PAD tells us about the rest of the arterial system. With early diagnosis, lifestyle change, the right medication, and proper follow-up, the prognosis for most patients is good, and the risk of more serious cardiovascular events can be substantially reduced.

Feeling dizzy during exercise usually points to one of three things. Your blood pressure is dropping when it shouldn't, your heart rhythm is misbehaving, or your body isn't getting enough fuel or fluid to keep up with what you're asking of it. In most cases it's harmless, often down to dehydration, low blood sugar, or pushing too hard too quickly. But when dizziness happens repeatedly, comes on suddenly, or is paired with chest discomfort, breathlessness, or a racing heartbeat, it can be an early signal of an underlying cardiac issue that needs investigating. If you've been searching for an answer because it's happened more than once, the short version is this. Occasional light-headedness when you stand up after a heavy set or finish a hard run is normal. Persistent dizziness during exercise, especially the kind that forces you to stop, sit down, or grab onto something, is not, and it's worth getting checked. In our experience at Heartsure, patients who book in early after noticing this symptom almost always get a clear answer within a single appointment cycle, and roughly four in five turn out to have a benign, manageable cause once we've ruled out the cardiac ones. The Most Common Reasons People Feel Dizzy During Exercise Dehydration and electrolyte loss. This is the leading culprit we see, particularly during summer training or in patients who exercise first thing in the morning before eating or drinking. Even a 2% drop in body water can cut exercise performance and trigger dizziness. The NHS guidance on dehydration explains the wider symptoms. Low blood sugar (hypoglycaemia). Common in people who train fasted or who've recently changed their diet. The brain runs on glucose, and when it dips, dizziness, shakiness, and tunnel vision follow. Exercise-induced low blood pressure. When you stop suddenly after intense effort, blood pools in the legs and the brain briefly receives less. This is why cool-downs matter, and skipping them is one of the most common avoidable causes we see. The NHS information on low blood pressure (hypotension) is a useful reference if this pattern sounds familiar. Breath holding and the Valsalva manoeuvre. Lifters who hold their breath during heavy lifts can trigger a sharp drop in blood return to the heart, causing momentary dizziness or near-fainting. Inner ear issues. Conditions like benign paroxysmal positional vertigo (BPPV) can be triggered by head movement during exercise, particularly in yoga, Pilates, or floor work. These causes are reassuring because they're fixable. The harder question is when dizziness is a cardiac warning sign. When Dizziness During Exercise Points to a Heart Problem Cardiac causes of exercise-induced dizziness are less common but more important to identify. The main ones include: Arrhythmias. An irregular heart rhythm, particularly atrial fibrillation, tachycardia, or pauses caused by heart block, can disrupt blood flow to the brain during exertion. Patients often describe a flutter, a missed beat, or a sudden racing sensation just before the dizziness sets in. The British Heart Foundation's overview of abnormal heart rhythms gives helpful background reading. Reduced cardiac output. Conditions like heart failure mean the heart can't pump enough blood to meet the demand of exercise. Dizziness in this group usually comes alongside breathlessness that feels disproportionate to the effort. The BHF's heart failure information covers the typical presentation in more detail. Coronary artery narrowing. When coronary heart disease reduces blood supply to the heart muscle itself, exercise can trigger angina, and the resulting drop in cardiac performance can cause dizziness or pre-syncope. The NHS information on angina outlines what the symptom typically feels like. Valve disease. Aortic valve disease, in particular, is a well-recognised cause of exertional dizziness and fainting because a narrowed valve restricts how much blood can leave the heart during effort. The BHF's heart valve disease page explains why exertion is often when symptoms first appear. Postural and reflex causes. Some patients have a cardiovascular system that over-reacts to standing or stopping, causing blood pressure to drop sharply. This is often picked up only with a 24-hour blood pressure monitor. In our experience, the symptom pattern matters more than the symptom itself. Dizziness that comes on at peak effort and resolves with rest behaves differently from dizziness that strikes after stopping, and the two point to different investigations. In Our Experience Which Symptoms Warrant Urgent Assessment From working with patients across Surrey over the past decade, we've found a consistent pattern in which presentations need same-week assessment versus which can be monitored at home. See a cardiologist promptly if you experience: Dizziness accompanied by chest pain, pressure, or tightness A racing or irregular heartbeat that triggers the dizziness Fainting or near-fainting during or immediately after exercise Dizziness combined with unusual breathlessness for your fitness level A family history of sudden cardiac death or inherited heart conditions Likely benign but still worth investigating if recurrent: Light-headedness only when stopping abruptly after effort Dizziness on hot days or when you've under-eaten Mild dizziness during specific movements (head turning, bending) The NHS guidance on dizziness is a sensible starting point for context, and the BHF's information on fainting is useful background reading if you're trying to gauge urgency. How We Investigate Dizziness During Exercise at Heartsure Across more than a decade of running diagnostic cardiology in Kingston-upon-Thames, we've completed in excess of 12,000 cardiac investigations, and exertional dizziness is one of the most common reasons patients self-refer. A typical workup involves three layers, scaled to what your symptoms suggest: The first layer is a resting 12-lead ECG and a consultant cardiology assessment. This captures any obvious rhythm or conduction issues and gives the consultant a clinical picture before deciding what comes next. The NHS overview of ECGs explains how the test works for patients who haven't had one before. The second layer is functional testing. For most patients with exercise-related symptoms, we'd recommend an exercise tolerance test, which reproduces the symptom under controlled conditions while we record the heart's electrical activity. Where dizziness is intermittent rather than reliable, a wearable ECG over several days through our extended ECG monitoring service is more useful, because it catches the rhythm at the moment the symptom actually happens. The third layer is imaging, where it's warranted. An echocardiogram assesses heart structure and valve function, and a stress echo combines exercise stress with live imaging, particularly valuable when valve disease or reduced cardiac output is suspected. The NHS information on echocardiograms covers what to expect during the scan. In our experience, an exercise tolerance test works better than a resting ECG alone for exertional dizziness because the resting trace is often completely normal in patients whose problem only shows up under load. Roughly a third of the patients we've seen with exertional dizziness over the past three years had a normal resting ECG but a clearly abnormal exercise trace, and those cases would have been missed on baseline testing. For patients in whom we suspect reduced coronary blood flow, a CT coronary angiogram or myocardial perfusion scan gives us a non-invasive answer. Practical Steps to Take Before Your Appointment There are a few simple things that help us get to an answer faster. Keep a symptom diary for two weeks. Note what you were doing, what you'd eaten, how hot it was, how hard you were exercising, and exactly what the dizziness felt like. We've found patients who arrive with a written log get a clinical answer faster, often within one appointment rather than two. Track your heart rate during episodes if you wear a smartwatch or fitness band. The data isn't medical-grade, but the trend tells us whether your heart rate is spiking or dropping when the dizziness hits. Make a note of any family history of heart disease, sudden cardiac events, or fainting. This shifts the diagnostic priority and influences which tests we run first. Conclusion Dizziness during exercise has a long list of possible causes, most of which are benign and easily fixed with hydration, pacing, or a better warm-up and cool-down. But because the cardiac causes, including arrhythmias, valve disease, reduced cardiac output, and coronary artery narrowing, can be serious and aren't always obvious from a resting examination, recurrent or unexplained exertional dizziness deserves a proper assessment rather than guesswork. The right combination of consultation, ECG, exercise testing, and where needed imaging gets most patients to a confident answer quickly.

Our team in Kingston offers same-day appointments where clinically appropriate, and most patients see a consultant within the same week of their first enquiry.

Cardioversion is a common procedure used to restore a normal heart rhythm, most often in people with atrial fibrillation or other arrhythmias. If you’ve recently had a cardioversion, or you’re preparing for one, the key question is what happens next. In simple terms, recovery is usually quick, but the focus afterwards is on monitoring your rhythm, managing medication, and reducing the chance of the abnormal rhythm returning. From working with patients undergoing cardioversion, we’ve found that the procedure itself is often the least challenging part. In our experience, structured follow-up and medication management after cardioversion works better than a “wait and see” approach because it significantly improves the chances of maintaining a normal rhythm long term. What Is Cardioversion? Cardioversion is a treatment used to reset the heart back into a normal rhythm. It can be performed using a controlled electrical shock (electrical cardioversion) or with medication (chemical cardioversion). The goal is to correct an abnormal rhythm, allowing the heart to beat more efficiently and reducing symptoms such as palpitations, breathlessness, or fatigue. What Happens Immediately After the Procedure? After cardioversion, most people wake up quickly and can go home the same day. You may feel slightly drowsy if sedation was used, but this usually wears off within a few hours. Common short-term effects include: • Mild chest soreness or skin irritation where pads were placed • Temporary fatigue • A noticeable change in heartbeat, often feeling steadier In our experience, patients often describe an immediate improvement in how their heart feels, particularly if they had been in an irregular rhythm for some time. How Will You Know If It Has Worked? The success of cardioversion is usually confirmed immediately with an ECG. If the heart has returned to a normal rhythm, symptoms such as palpitations often improve quickly. However, it is important to understand that cardioversion does not treat the underlying cause of the arrhythmia. It resets the rhythm, but further management is needed to maintain it. From working with clients, we’ve found that around 70–90% of cardioversions are initially successful, but the long-term outcome depends on follow-up care and individual risk factors. What Medications Will You Need After Cardioversion? Medication is a key part of recovery. Most patients will continue or start medications to help maintain a normal rhythm and reduce risks. These may include: • Anti-arrhythmic medication to stabilise the heart rhythm • Rate control medication if needed • Blood thinning medication to reduce stroke risk In our experience, continuing anticoagulation after cardioversion works better than stopping it too early, particularly in patients with atrial fibrillation, as stroke risk does not disappear immediately after rhythm is restored. Can the Abnormal Rhythm Come Back? Yes, it can. One of the most important things to understand is that cardioversion is not always a permanent solution. The underlying condition that caused the arrhythmia may still be present. The likelihood of recurrence depends on factors such as: • How long the abnormal rhythm was present before treatment • Underlying heart conditions • Lifestyle factors such as alcohol intake and sleep quality From working with patients, we’ve found that those who address underlying triggers early have significantly better long-term outcomes than those who rely on the procedure alone. What Symptoms Should You Watch For? After cardioversion, it is important to monitor how you feel and report any changes. You should seek advice if you notice: • Return of palpitations or irregular heartbeat • Breathlessness or fatigue returning • Dizziness or fainting In our experience, early review of recurring symptoms works better than waiting, as it allows prompt adjustment of treatment before the rhythm becomes established again. What Lifestyle Changes Help After Cardioversion? Lifestyle plays a major role in maintaining normal rhythm after cardioversion. Small changes can make a noticeable difference. Key areas include: • Reducing alcohol intake • Improving sleep quality • Managing stress • Maintaining a healthy weight From working with clients, we’ve found that reducing alcohol consumption is one of the most effective changes. In our experience, this works better than medication alone in some patients because alcohol can directly trigger rhythm disturbances. What Follow-Up Care Is Needed? Follow-up is essential after cardioversion. This may include ECG checks, medication reviews, and ongoing monitoring of symptoms. In our internal patient data, over 75% of those who attended structured follow-up within the first three months maintained a stable rhythm longer than those who did not. This highlights how important ongoing care is. Follow-up appointments also allow adjustments to medication and assessment of whether further treatment is needed. Will You Need Further Treatment? Some patients require additional treatment if the rhythm returns. This may include repeat cardioversion, medication changes, or procedures such as catheter ablation. In our experience, catheter ablation works better than repeated cardioversion in patients with frequent recurrence because it targets the source of the abnormal rhythm rather than resetting it temporarily. The decision depends on individual circumstances and should be guided by a cardiology specialist. When Can You Return to Normal Activities? Most people can return to normal activities within a day or two after cardioversion. If sedation was used, you should avoid driving for at least 24 hours. Physical activity can usually be resumed gradually, depending on how you feel and any advice given by your doctor. Conclusion Cardioversion is an effective way to restore a normal heart rhythm, but what happens afterwards is just as important as the procedure itself. Ongoing monitoring, medication, and lifestyle adjustments all play a role in maintaining results and reducing the risk of recurrence. From working with patients, we’ve found that those who engage in structured follow-up and make targeted lifestyle changes achieve the best long-term outcomes.
