What echocardiogram looks for
Informed by recognized medical guidance
Overview
An echocardiogram is a safe, painless ultrasound test that uses sound waves to create moving pictures of your heart. It shows how well your heart is pumping, how your heart valves are working, and if there are any problems with the heart muscle or lining.
Key facts
- It is like a video of your heart, not just a single picture.
- No radiation is involved — it uses sound waves, like a pregnancy scan.
- It can be done while you rest or after light exercise (stress echo).
Yes, echocardiograms are very common. Millions are performed worldwide each year to check for heart conditions.
Anyone who needs to have their heart function checked — from newborns to older adults — may have an echocardiogram. Your doctor may recommend one if you have symptoms like shortness of breath, chest pain, palpitations, or an irregular heartbeat.
Symptoms
- Chest pain that does not go away
- Severe difficulty breathing or gasping for air
- Fainting or passing out for no clear reason
- Sudden cold sweat, nausea, or lightheadedness with chest pain
- ⚠New or worsening shortness of breath that interferes with daily life
- ⚠Heart palpitations that last several minutes or come with dizziness
- ⚠Swelling in your legs or belly that gets worse quickly
- ⚠You feel a constant fluttering in your chest
Common symptoms
- Shortness of breath, especially when active or lying flat
- Chest pain or tightness
- Feeling your heart race, pound, or skip beats (palpitations)
- Swelling in your ankles, feet, or legs (oedema)
- Feeling faint or dizzy
Symptoms in children
- Rapid breathing or difficulty feeding
- Turning blue or pale (cyanosis)
- Poor weight gain or tiredness
- Heart murmur heard by a doctor
Symptoms in older adults
- Worsening shortness of breath with activity
- Increased swelling in the legs
- Sudden confusion or lightheadedness
- Falls or feeling very weak
Causes
Main causes
- An echocardiogram is done to look for heart problems — it does not have a cause. Common reasons include chest pain, shortness of breath, heart murmur, or abnormal ECG.
Risk factors
- High blood pressure (hypertension)
- Previous heart attack or heart disease
- Heart valve disease or infection
- Heart failure symptoms
- Family history of heart problems
When to see a doctor
See a doctor urgently if:
- Chest pain that does not go away after a few minutes
- Severe shortness of breath that comes on suddenly
- Fainting or collapsing
Book a routine appointment if:
- You have been advised to have an echocardiogram as part of a check-up for a heart condition
- You have new or worsening symptoms like swelling, palpitations, or tiredness
- You have a known heart condition that needs monitoring
Diagnosis
An echocardiogram is performed by a specially trained sonographer or cardiologist. You lie on a bed while a small probe is moved over your chest. It sends sound waves that create images of your heart.
Tests that may be done
- Transthoracic echocardiogram (standard — probe on chest)
- Stress echocardiogram (before and after exercise or medicine)
- Transoesophageal echocardiogram (probe down the throat for clearer views of the back of the heart)
What to expect at your appointment
You will remove clothing from your upper body and lie on a bed. A clear gel is applied to your chest before the probe is moved around. It may be slightly cold but is painless. The test usually takes 30–60 minutes. You can go home straight after.
Treatment
An echocardiogram itself is a test, not a treatment. The results help your doctor decide if you need treatments such as medicines, lifestyle changes, or procedures. Treatment depends on what the echocardiogram finds — for example, valve problems, heart weakness, or inflammation.
Self-care at home
- No special preparation is needed unless told otherwise (you may be asked not to eat for a few hours before a stress echo).
- Wear comfortable clothing that you can easily remove from the top.
Medical treatments
Depending on the findings, treatment may include medication to help your heart pump better, control your heart rate, or reduce fluid build-up. Valve problems may need monitoring, medication, or sometimes surgery. Always follow your doctor’s advice about any prescribed medicines. Do not change or stop them without speaking to your healthcare provider.
When is surgery considered?
If the echocardiogram shows severe valve disease, a hole in the heart, or other structural issues, your doctor may discuss surgery or a catheter-based procedure. These are usually planned and not urgent, unless you are very unwell.
Living with this condition
After an echocardiogram, you can resume normal activities immediately. If you have been diagnosed with a heart condition, your doctor will give you advice on managing it day to day.
Lifestyle tips
- Stay active as much as your doctor advises
- Avoid smoking and limit alcohol
- Manage stress with relaxation or gentle exercise
- Keep regular appointments with your healthcare team
Diet and exercise
Eat a balanced diet low in salt and saturated fat. Include plenty of fruits, vegetables, whole grains, and lean protein. Do moderate exercise like walking or cycling for 30 minutes most days, as your doctor agrees.
Mental health and emotional wellbeing
Waiting for test results or learning you have a heart condition can be worrying. It is normal to feel anxious or low. Talk to your doctor or a counsellor if these feelings last. You are not alone.
Prevention
Echocardiograms are tests, not conditions, so they cannot be prevented. But many heart problems can be prevented or delayed with a healthy lifestyle.
Vaccines
Keep up to date with flu and pneumonia vaccines if you have a heart condition — they help prevent infections that could worsen heart problems.
Screening programmes
Screening echocardiograms are not routine for everyone. Your doctor may recommend one if you have symptoms or a strong family history of heart disease.
Complications
If left untreated
- An echocardiogram has no risks (no radiation). However, if a heart problem is left undiagnosed, it could lead to serious complications such as heart failure, stroke, or rhythm problems.
Long-term outlook
An echocardiogram gives your doctor vital information. If any problem is found, there are many effective treatments available. Most heart conditions can be managed well, and many people live full, active lives with the right care. Early detection often leads to better outcomes.
