Echocardiography

Echocardiography or an “echo” uses sound waves to create images of the heart. During this procedure, a technologist uses a hand-held scanning device that creates digital images for a cardiologist to review.

These images help the cardiologist learn more about heart size and function, including the chambers and valves. Sometimes this is performed both prior to and after stress testing to improve detection of coronary artery blockages.
