Echocardiography (2D Echo with Doppler)
An ultrasound scan of your heart that shows how well it pumps and whether its valves open and close properly, with no needles and no radiation.
- Test duration
- 20 to 40 minutes
- Anaesthesia
- None needed
- Hospital stay
- None, you go home straight after
- Results
- Usually the same day

Overview
Your ankles swell by evening and you're breathless by the first-floor landing. Or you've just had a heart attack, and everyone wants to know how much damage it did. Either way, the next step is very often an echo.
Echocardiography is an ultrasound of the heart, using the same kind of probe as a pregnancy scan. Moved over your chest with some gel, it builds a moving picture of the chambers, walls and valves. Doppler adds the direction and speed of blood flow, which shows leaking or narrowed valves and helps estimate the pressure in your lungs.
An echo shows how strongly the heart pumps, whether the muscle is thickened or damaged, how each valve is working and whether there's fluid around the heart. It can't see inside the coronary arteries, so a normal echo doesn't rule out a blockage.
Our cardiology unit has 2D echocardiography with Doppler. For people with a known heart condition, we repeat the echo at intervals to track changes and adjust treatment.
Why the test is done
An echo is used to find the cause of symptoms and to follow known heart problems over time.
- Breathlessness, swollen ankles or tiredness that could mean heart failure
- A heart murmur, in adults or children
- After a heart attack, to see how the pumping has been affected
- Long-standing high blood pressure, which can thicken the heart muscle
- A stroke or palpitations, to look for a clot or a structural cause in the heart
- Some cancer treatments that can weaken the heart, and follow-up of valve disease or heart problems in pregnancy
Types of test
Standard echo
The probe stays on the outside of your chest (a transthoracic echo). It answers most questions and is the test most people need.
Stress echo
Pictures are taken before and after exercise, or after a medicine that makes the heart work harder. Muscle that stops moving well under stress suggests a narrowed artery.
Transoesophageal echo (TOE)
A thin probe passes down the food pipe, which lies right behind the heart, after a throat spray and sedation. It gives clearer views of the valves and of clots, and it's arranged only when a standard echo can't answer the question.
Preparing for the test
- For a standard echo, eat, drink and take your medicines as usual
- Wear a two-piece outfit, such as a kurta or shirt with trousers, since you'll undress to the waist and wear a gown
- Bring previous echo reports, ECGs and your medicine list
- For a stress echo, wear walking shoes and ask whether to skip beta-blockers that morning. Stop them only on your cardiologist's advice
- For a transoesophageal echo, don't eat or drink for about 6 hours, and bring someone to take you home
- For a young child, bring a feed or a favourite toy. A calm child gives clearer pictures
What happens during the test
- 01
Getting settled
You lie on the couch in a gown, usually turned onto your left side, with three ECG stickers on your chest.
- 02
Gel and probe
Cool gel goes on, and the probe is pressed between the ribs, under the breastbone and sometimes at the base of the neck. Firm pressure can be uncomfortable for a moment but shouldn't hurt.
- 03
Doppler measurements
Any whooshing sounds are the blood flow being measured. You may be asked to hold your breath or roll further over for a clearer view.
- 04
Finishing up
The gel is wiped off and you can dress and leave. Most scans take 20 to 40 minutes.
Understanding your results
The report describes each chamber and valve and ends with a short impression, which is the part to read first. Your cardiologist usually goes through it with you the same day.
The number most people look for is the ejection fraction (EF), the share of blood the main pumping chamber pushes out with each beat. About 55% or more is usually normal and 50 to 54% is borderline. From 41% to 49% is mildly reduced, and 40% or below means a weak heart muscle. "Regional wall motion abnormality" means part of the wall isn't moving well, often after a heart attack. "LVH" is thickened muscle, commonly from high blood pressure. Grade 1 diastolic dysfunction, a stiffer relaxing phase, is very common after 50.
Valves are graded for leakage (regurgitation) or narrowing (stenosis) as trivial, mild, moderate or severe. Trivial and mild leaks are common in healthy people. Moderate or severe findings usually mean treatment, closer follow-up or further tests such as a coronary angiogram.
Benefits and risks
Benefits
- Painless, with no needles and no radiation, so it's safe in pregnancy and for newborns
- Shows the heart pumping and the valves moving in real time
- Results are usually available the same day
- Easy to repeat, so changes can be tracked over the years
Possible risks
- A standard echo has no known risks, though the probe pressure can be briefly uncomfortable
- Mild skin redness from the ECG stickers
- Less clear pictures in people with obesity or lung disease, or after chest surgery
- After a transoesophageal echo, a sore throat for a day. Injury to the food pipe is very rare
After the test
- 01
Straight after
After a standard or stress echo you can eat, work and drive as normal.
- 02
After a transoesophageal echo
Wait about an hour before eating or drinking, until your throat is no longer numb. Don't drive or ride for the rest of the day because of the sedation.
- 03
Follow-up
If a problem is found, your cardiologist will explain the next step, which may be a change in medicines, another test or a repeat echo in 6 to 12 months.
When to call your doctor
- Chest pain lasting more than 10 to 15 minutes. Go to the emergency department rather than waiting for your report
- Breathlessness at rest or when lying flat, or waking up gasping
- Fainting, or a racing, irregular heartbeat with dizziness
- A weight gain of 2 kg or more in a few days, with swollen legs
- After a transoesophageal echo, worsening throat or chest pain, trouble swallowing or vomiting blood
Call us on +91-8826000033 or come straight to our 24/7 emergency department.
Other tests
ECG
A 10-second electrical tracing. It picks up rhythm problems and old heart attacks but says little about the valves or pumping strength.
Cardiac MRI
Gives very detailed pictures of the heart muscle, which helps when echo images are unclear or when inflammation or scarring is suspected. Some metal implants rule it out.
Tests for blocked arteries
An echo can't show narrowed coronary arteries. A treadmill test, CT coronary angiogram or catheter angiogram answers that question.
