This article will help you understand what an Echo test is
As a heart health specialist, I'm often asked about echocardiograms – or "echo tests" as they're commonly called. These vital diagnostic tools provide a window into one of our most essential organs, yet many people feel anxious when their doctor recommends one. Today, I'll walk you through everything you need to know about an echo test, from how it works to what to expect during your appointment.
Understanding the Basics of an Echo Test
An echo test is essentially an ultrasound of your heart. Instead of using radiation like X-rays or CT scans, echo tests use high-frequency sound waves to create detailed images of your heart's structure and function. The beauty of this technology is that it's entirely non-invasive and safe for everyone – including pregnant women and children.
Think of it as taking a moving picture of your heart in action. Your Cardiologist can see how well your heart chambers and valves are working, assess blood flow, and identify potential problems that might not be detectable through other methods.
Why Would You Need an Echo Test?
There are several reasons your doctor might recommend an echo test:
To diagnose a heart valve problem
To check for signs of heart failure
To assess damage after a heart attack
To monitor heart function during pregnancy
To evaluate congenital heart defects
To check for blood clots or tumours (though these are rare findings)
The test gives your healthcare team valuable information about how efficiently your heart is pumping and whether there are any structural abnormalities that need attention.
Types of Echo Tests Available
Not all echo tests are created equal. Depending on what your doctor is looking for, they might recommend one of the following common types:
Transthoracic Echocardiogram (TTE)
This is the standard echo test most people receive. A technician simply moves a probe (transducer) across your chest to capture images of your heart. It's quick, painless, and requires no special preparation.
Transoesophageal Echocardiogram (TOE)
For this more specialised echo test, a small probe is guided down your throat to get clearer images from behind your heart. You'll typically receive mild sedation beforehand and will need to fast for about six hours prior to the procedure.
Stress Echocardiogram
This variation assesses how your heart functions under physical stress. You'll either exercise on a treadmill or receive medication that mimics the effects of exercise before having the echo test performed. It's particularly useful for diagnosing coronary artery disease.
Fetal Echocardiogram
For expectant mothers with a family history of heart conditions, this specialised echo test monitors a baby's heart development during pregnancy.
What to Expect During Your Echo Test
If you've been scheduled for a standard transthoracic echo test (TTE), here's what typically happens:
You'll change into a hospital gown, leaving your chest accessible
You'll lie on your left side on an examination table
A technician will place small adhesive electrodes on your chest to monitor your heart rhythm
They'll apply a clear gel to your chest (which might feel cold)
The technician will press a handheld device (transducer) against different parts of your chest
You might be asked to hold your breath briefly or change positions
The entire procedure usually takes 20–30 minutes
Throughout the test, you'll hear swooshing sounds as the machine captures images of blood flowing through your heart. The process is painless, though you might feel mild pressure from the transducer.
For a transoesophageal echo test, the preparation is more involved. You'll need to fast beforehand, and you'll receive a mild sedative. The procedure takes slightly longer, and you might experience some throat soreness afterward. You'll also need someone to drive you home.
Getting Your Echo Test Results
One of the advantages of an echo test is the quick turnaround on results. If you're having the test done privately, you might receive your results the same day. Through the NHS, you'll typically get them within a few days to a week.
Your doctor will review the images with you, explaining what they show about your heart's structure and function. They'll point out any abnormalities and discuss the next steps if treatment is needed.
Accessing Echo Tests in the UK
Echo tests are widely available throughout the UK through both the NHS and private healthcare providers. If your GP recommends an echocardiogram, you can expect:
Through the NHS
The test will be free, but waiting times vary by region and urgency. Generally, you might wait between 2–8 weeks, though urgent cases are prioritised.
Through Private Healthcare
If you prefer not to wait or want more flexibility with appointment times, private echo tests are widely available. A standard TTE costs between £200–£500, depending on the provider and location. Specialised tests like TOEs or stress echocardiograms cost more, ranging from £500–£1,500.
Many private health insurance plans cover echo tests, so check your policy before booking if you're insured.

Why Heart Health Monitoring Matters
I've seen firsthand how early detection through an echo test has saved lives. Conditions like aortic stenosis or mitral valve regurgitation can be spotted before symptoms become severe, potentially reducing your risk of a heart attack by up to 30% with timely intervention.
With cardiovascular disease affecting nearly 7.6 million people in the UK, proactive heart monitoring has never been more important. Since the pandemic, we've seen increased interest in heart screening, with more people researching these tests online than ever before.
Is an Echo Test Right for You?
If you're experiencing symptoms like chest pain, shortness of breath, or heart palpitations, or if you have a family history of heart disease, discussing an echo test with your doctor might be worthwhile. Even for those without symptoms, heart screenings can catch problems early — especially for adults over 65 or those with risk factors like high blood pressure or diabetes.
Remember, while echo tests are incredibly useful, they're just one tool in the cardiovascular diagnostic arsenal. Your doctor might recommend additional tests like an ECG or blood work to get a complete picture of your heart health.
Final Thoughts
An echo test is one of modern medicine's most valuable non-invasive diagnostic tools. It provides detailed information about your heart's structure and function without radiation, discomfort, or significant risk.
If your doctor has recommended an echocardiogram, rest assured that you're taking an important step toward understanding and protecting your heart health. The test itself is quick and painless, and the information it provides can be life-saving.
