Stress Echocardiogram

An echocardiogram, also called an echo is a test that uses ultrasound waves to produce images of the heart. A microphone-like device called a transducer sends out ultrasound waves that bounce off the heart to produce images of the heart when combined with exercise on a treadmill. The echo can detect areas of the heart that are not receiving enough blood flow. A stress echo is especially useful in identifying blockages in the arteries that supply blood flow and oxygen to the heart.
