Echocardiogram (ECHO)

This test uses ultrasound waves to look at the structure of the heart. It is useful for people whose ECG shows changes that could be caused either by a channelopathy or by uninherited heart disease that has damaged the heart. An echocardiogram can also detect inheritable conditions such as cardiomyopathy and mitral valve prolapse.

The operator puts some clear gel on your chest and then places an ultrasound probe on it. The probe sends ultrasound beams into your body and their reflections are detected and used to generate images of the heart.

You can see different parts of your heart on a screen as the probe is moved around on your chest.

The test is similar to the ultrasound scan that is used to examine a pregnant woman’s unborn baby. It is completely painless.
