An echocardiogram (also called an echo) is a type of ultrasound test that uses high-pitched sound waves that are sent through a device called a transducer. The device picks up echoes of the sound waves as they bounce off the different parts of your heart. These echoes are turned into moving pictures of your heart that can be seen on a video screen.
Echocardiograms can be done in different ways. The types include transthoracic, transesophageal, and stress echocardiograms. A Doppler echo shows blood flow through the heart and blood vessels. It can be done during any of these types of echocardiograms.
The different types of echocardiograms are:
An echocardiogram is done for many reasons. It can measure how well your heart is pumping blood. It can show blood flow through the heart and blood vessels. It may be done to look for problems with your heart size, thickness, shape, and muscle movement. The test can also be used to see how well your heart valves work and if there are blood clots or tumours inside the heart.
Results are usually available within one day. If the test is done by a cardiologist, the results may be available immediately after the test.
The heart chambers and walls of the heart are of normal size and thickness, and they move normally.
Heart valves are working normally, with no leaks or narrowing. There is no sign of infection.
The amount of blood pumped from the left ventricle with each heartbeat (ejection fraction) is normal.
There is no excess fluid in the sac surrounding the heart, and the lining around the heart is not thickened.
There are no tumours and blood clots in the heart chambers.
Heart chambers are too big. The walls of the heart are thicker or thinner than normal. A thin heart wall may mean poor blood flow to the heart muscle or an old heart attack. A thin, bulging area of the heart wall may indicate a bulge in the ventricle (ventricular aneurysm). The heart muscle walls do not move normally because of a decreased blood supply from narrowed coronary arteries.
One or more heart valves do not open or close properly (are leaking) or do not look normal. Signs of infection are present.
The amount of blood pumped from the left ventricle with each heartbeat (ejection fraction) is lower than normal.
There is fluid around the heart (pericardial effusion). The lining around the heart is too thick.
A tumour or blood clot may be found in the heart.
