Preparing for echocardiogram
Informed by recognized medical guidance
Overview
An echocardiogram (often called an 'echo') is a safe, painless ultrasound scan that uses sound waves to create moving pictures of your heart. It helps doctors see how well your heart is working, including its size, shape, and how blood flows through it.
Key facts
- No special preparation is usually needed for a standard echocardiogram.
- It is not invasive — no needles or incisions are involved.
- The test takes about 30 to 60 minutes and you can go home right after.
Echocardiograms are very common. Millions are done each year around the world to check heart health.
Anyone can have an echocardiogram — from babies to older adults. Your doctor may recommend one if you have symptoms like chest pain, shortness of breath, or an irregular heartbeat, or to monitor a known heart condition.
Symptoms
- Sudden, severe chest pain that does not go away
- Difficulty breathing or gasping for air
- Fainting or collapsing
- Blue lips or face
- ⚠Chest pain that comes and goes, especially with activity
- ⚠New or worsening shortness of breath
- ⚠Rapid or irregular heartbeat that does not stop
- ⚠Swelling that suddenly gets worse
Common symptoms
- Chest pain or discomfort
- Shortness of breath, especially during activity
- Irregular or fast heartbeat (palpitations)
- Unexplained fatigue or weakness
- Swelling in the legs, ankles, or feet
Symptoms in children
- Difficulty feeding or breathing
- Blue tint around the lips or skin (cyanosis)
- Poor growth or weight gain
- Heart murmur heard by a doctor
Symptoms in older adults
- Shortness of breath with minimal activity
- Dizziness or fainting spells
- Swelling in the lower body
- Increased fatigue or confusion
Causes
Main causes
- A heart murmur — an unusual sound when blood flows through the heart
- Suspected heart valve disease, such as a leaky or narrowed valve
- Heart failure, where the heart does not pump blood as well as it should
- Heart attack or other damage to the heart muscle
- Irregular heartbeat (arrhythmia)
Risk factors
- High blood pressure that is not well controlled
- High cholesterol
- Diabetes
- A family history of heart disease
- Smoking or heavy alcohol use
When to see a doctor
See a doctor urgently if:
- If you have new chest pain, shortness of breath, or fainting, seek medical help immediately — call your local emergency number.
Book a routine appointment if:
- If you have a known heart condition and your doctor recommends a follow-up echocardiogram
- If you have risk factors like high blood pressure or diabetes and your doctor wants to check your heart
Diagnosis
A doctor or a specialist (cardiologist) uses an echocardiogram to look at your heart. The test can also be done during exercise (stress echo) or with a probe passed down your throat (transesophageal echo) if clearer images are needed.
Tests that may be done
- Transthoracic echocardiogram (TTE) — the standard echo, done by moving a small device (transducer) over your chest
- Stress echocardiogram — done before and after exercise or medication to see how your heart responds
- Transesophageal echocardiogram (TOE) — a flexible probe is gently passed into your oesophagus behind the heart for more detailed images
- Doppler echocardiogram — measures blood flow through the heart and valves
What to expect at your appointment
You will lie on a bed or table. A trained sonographer or doctor applies a cool gel to your chest and moves a small handheld device (transducer) over the area. They may ask you to breathe slowly or hold your breath briefly. You will hear a whooshing sound from the machine. The entire process is painless and takes about 30 minutes. You can eat, drink, and drive normally afterward unless you had sedation for a TOE.
Treatment
The echocardiogram itself is not a treatment — it is a diagnostic test. After the scan, a heart specialist (cardiologist) will review the images and discuss the results with you. Any treatment will depend on what the test shows.
Self-care at home
- Follow any instructions given by your healthcare team before the test (for example, if you have a stress echo, they may ask you to avoid caffeine or certain medications)
- Wear comfortable, loose clothing that allows access to your chest
- Bring a list of your current medications to show the doctor or sonographer
Medical treatments
If the echocardiogram finds a problem, your doctor may recommend lifestyle changes, medications (such as blood pressure or heart rhythm medications, but never specific names), or procedures like valve repair or replacement. Always follow your doctor's advice.
When is surgery considered?
In rare cases, if the echocardiogram shows severe valve disease or other serious structural problems, surgery may be recommended. Your cardiologist will explain the options and refer you to a heart surgeon if needed.
Living with this condition
After an echocardiogram, you can return to normal activities right away. If you had a transesophageal echo with sedation, you may need someone to drive you home and rest for the day.
Lifestyle tips
- Keep up with any heart-healthy habits your doctor has recommended, such as eating well and staying active
- Attend all follow-up appointments to review your test results
- Carry a list of your heart medications if you take any
Diet and exercise
No special diet or exercise is needed before or after a standard echocardiogram. For a stress echo, follow your doctor's instructions about eating beforehand. In general, a heart-healthy diet low in salt, sugar, and unhealthy fats, along with regular exercise, is good for your heart.
Mental health and emotional wellbeing
Waiting for test results can be stressful. Talk to your doctor about how you are feeling. Many people find it helpful to bring a friend or family member for support on the day of the test.
Prevention
An echocardiogram is not something you prevent — it is a test. But taking care of your heart can help reduce the need for repeated tests. Maintain a healthy weight, do not smoke, limit alcohol, and manage conditions like high blood pressure and diabetes.
Complications
If left untreated
- If a heart problem is found but not treated, it could lead to worsening symptoms or more serious conditions like heart failure or stroke.
Long-term outlook
The echocardiogram itself is very safe and causes no harm. Any findings are caught early, which gives you and your doctor the best chance to manage your heart health. With proper follow-up, most heart conditions can be treated effectively.
