1 Heart defects. 2  Many heart defects can be detected with an echocardiogram, including problems with the heart chambers, abnormal connections between the heart and major blood vessels, and complex heart defects that are present at birth. 3  Echocardiograms can even be used to monitor a baby's heart development before birth.
An echocardiogram uses an ultrasound machine to take a scan of your heart. It is carried out by a specially qualified technician and is sometimes just called an âechoâ, âecho heartâ or âechogramâ. Ultrasound machines detect sounds with such high frequencies that they cannot be heard by humans. The test is called an echocardiogram because the sound âbouncesâ or echoes back from the heart tissue to give an accurate picture of the heart. For example, ultrasound passes easily through fluid so there is little echo from the blood in the heart, which would otherwise affect the result.
