An echocardiogram, also called an echo, is an ultrasound of the heart. This important procedure uses sound waves to produce images of the heart. A computer records the images and can create a moving picture of your heart. From this test, your doctor evaluates the health of your heart and blood flow.

Echocardiograms can help detect and determine treatment for heart disease, heart attacks and vascular disease that can lead to stroke. Unlike an x-ray, there is no radiation with this test.
