An echocardiogram, commonly known as an Echo, uses ultrasound to examine the heart. It is a similar technique to the scans performed in pregnant women to examine the unborn baby and is completely safe and painless.
Echo is the mainstay diagnostic test for evaluation of the heart structure and function. It provides information on how the heart is put together and how it is working. Measurements are obtained to assess the size of the heart chambers and the thickness of the heart muscle. Echo also measures the pumping action of the heart, the function of heart valves and determines whether there are any congenital abnormalities.
