Overview
An echocardiogram (often called an “echo”) is a test that uses sound waves (ultrasound) to create a moving picture of your heart. It shows the size, shape, and movement of your heart's chambers and valves, and how well blood is being pumped. Think of it as a ‘live video’ of your heart working – safe, painless, and without using radiation.
Key facts
An echocardiogram is painless and has no known side effects.
It takes about 30–60 minutes and can be done in a clinic, hospital, or doctor's office.
It helps doctors diagnose conditions like heart valve problems, heart muscle weakness, or fluid around the heart.
Most people do not need any special preparation – you can eat and drink normally.
Questions about this article
Yes, echocardiograms are one of the most common heart tests performed worldwide. Millions are done each year to check for heart problems or monitor known conditions.
Anyone can need an echocardiogram – children, adults, and older people. It is often used when a doctor suspects a heart problem, or to monitor someone with a known heart condition, like heart failure or a valve defect.
Symptoms
Call emergency services immediately if you notice:
Sudden severe chest pain that does not go away
Difficulty breathing that comes on suddenly
Fainting (passing out) with no warning
Pain or pressure in the chest that spreads to your arm, jaw, or back
See a doctor urgently (same day) if you notice:
⚠Chest pain that comes and goes, especially with activity
⚠New palpitations that last more than a few minutes
⚠Swelling in your legs that suddenly gets worse
⚠Shortness of breath that wakes you up at night
Common symptoms
Shortness of breath – especially during activity or when lying flat
Chest pain or discomfort
Feeling your heart racing, fluttering, or skipping beats (palpitations)
Swelling in your legs, ankles, or feet (oedema)
Extreme tiredness (fatigue) that doesn't improve with rest
Dizziness or fainting spells
Symptoms in children
Difficulty feeding or tiring easily during feeds (in babies)
Poor weight gain or growth
Blue tinge to the skin, lips, or nails (cyanosis)
Rapid breathing or shortness of breath during play
Fainting during exercise or sport
Symptoms in older adults
Worsening shortness of breath with everyday activities
Unexplained falls or feeling light-headed
Swelling in the lower legs that is new or getting worse
Sudden increase in tiredness or confusion
Causes
Main causes
Your doctor may order an echocardiogram to check for heart conditions. Common reasons include: suspected heart valve problems (leaky or narrowed valves), heart muscle weakness (cardiomyopathy), heart failure, blood clots in the heart, or infection of the heart lining (endocarditis).
It is also used to look at the structure of the heart if a heart murmur is heard, or to see how well a treatment is working.
Risk factors
Having high blood pressure for a long time
A history of heart attack or heart disease
Diabetes, obesity, or high cholesterol
A family history of heart conditions (like cardiomyopathy or valve disease)
Infections that can affect the heart, such as rheumatic fever
Certain chemotherapy drugs or radiation therapy to the chest
When to see a doctor
See a doctor urgently if:
If you have sudden shortness of breath, chest pain, or fainting – call your local emergency number immediately.
If you have new swelling in your legs or trouble breathing that gets worse quickly – see a doctor the same day.
Book a routine appointment if:
If you have mild but persistent symptoms like tiredness, a fluttering feeling in your chest, or mild ankle swelling, make an appointment to discuss them with your doctor.
If your doctor hears a heart murmur during a check-up, they may recommend an echocardiogram as a routine test.
Echocardiograms are very safe and routine tests. Most people have nothing to worry about. If your doctor suggests one, it's usually to get a clearer picture of your heart's health – not because something is definitely wrong.
Diagnosis
An echocardiogram is the test itself – it helps diagnose or monitor heart conditions. A specially trained technician (sonographer) or a doctor performs it. You lie on a bed, and a small handheld probe (transducer) is moved over your chest after a cool gel is applied. The probe sends sound waves that create images of your heart on a screen.
Tests that may be done
Transthoracic echocardiogram (TTE) – the standard type done through the chest wall
Transesophageal echocardiogram (TOE/TEE) – a small probe is passed down your food pipe (oesophagus) for clearer images of the back of the heart. You are usually given a sedative.
Stress echocardiogram – images are taken before and after exercise (or with medication that makes your heart beat faster) to see how your heart responds to stress.
Doppler echocardiogram – measures the speed and direction of blood flow through the heart and valves.
What to expect at your appointment
For a standard echo, you will be asked to remove clothing from the upper body and lie on your left side. A gel is applied to your chest, and the technician moves the probe gently over your skin. You may be asked to breathe slowly or hold your breath for a few seconds. The test is painless. You can go home or back to normal activities immediately after.
Treatment
An echocardiogram itself is not a treatment – it provides information that helps your doctor decide what treatment you need. Based on the results, treatments might include lifestyle changes, medicines, or procedures.
Self-care at home
Eat a heart-healthy diet low in salt, saturated fats, and added sugars.
Stay physically active – aim for at least 150 minutes of moderate activity per week, unless your doctor advises otherwise.
Manage stress through relaxation techniques, deep breathing, or talking to a counsellor.
If you smoke, seek help to quit – smoking damages your heart and blood vessels.
Limit alcohol to within recommended guidelines.
Medical treatments
Your doctor may recommend medications to control blood pressure, reduce fluid buildup, strengthen the heart's pumping action, or prevent blood clots. They will choose the best one for you based on your specific condition. You may also be referred to a heart specialist (cardiologist) for further evaluation or treatment.
When is surgery considered?
If an echocardiogram shows severe valve disease, a hole in the heart, or other structural problems, surgery or a catheter-based procedure may be needed. Your healthcare team will discuss the options with you in detail.
Living with this condition
For most people, an echocardiogram is a one-time test. If you have a chronic heart condition, you may need regular echoes to monitor your health. Follow your doctor's advice about check-ups and any lifestyle changes. Keep a list of your medicines and symptoms to discuss at appointments.
Lifestyle tips
Follow a heart-friendly diet – more fruits, vegetables, whole grains, lean proteins, and healthy fats.
Stay active in a way that feels good for you – walking, swimming, cycling, or gentle yoga.
Monitor your weight and watch for sudden increases, which may signal fluid retention.
Learn to check your own pulse and know what is normal for you.
Avoid heavy lifting or straining if you have certain valve or heart muscle conditions.
Diet and exercise
A balanced diet with plenty of fibre, potassium-rich foods (like bananas, spinach), and limited salt is helpful for your heart. Exercise that raises your heart rate moderately, like brisk walking, can improve circulation and stamina. Always talk to your doctor before starting a new exercise programme, especially if you have a heart condition.
Mental health and emotional wellbeing
Waiting for results or learning you have a heart condition can be worrying. It's normal to feel anxious, scared, or low. Talk to your family, friends, or a professional. Connecting with others who have similar experiences can also help.
Prevention
An echocardiogram itself does not prevent heart disease, but finding problems early can help prevent them from getting worse. You can lower your risk of needing an echo for serious reasons by keeping your heart healthy: control blood pressure, don't smoke, eat well, stay active, and manage diabetes.
Complications
If left untreated
If a heart condition shown on an echo is not treated, it can worsen over time and lead to heart failure, irregular heart rhythms (arrhythmias), or stroke.
Untreated valve disease can place extra strain on the heart and eventually damage it permanently.
Heart muscle problems (cardiomyopathy) can progress and limit your ability to do everyday activities.
Long-term outlook
An echocardiogram is a powerful tool that helps doctors catch heart problems early. When conditions are found and treated, most people can lead long, active lives. Advances in heart care mean that even serious diagnoses often have effective treatments available. Stay in close touch with your healthcare team and follow their advice.
