• An electrocardiogram (EKG or ECG) and an echocardiogram (echo) are tests that help find problems with the heart muscle, valves, or rhythm. An echocardiogram is a test that uses ultrasound to show how your heart muscle and valves are working. The sound waves make moving pictures of your heart so your doctor can get a good look at its size and shape.

    Why Do I Need an Echocardiogram?


    Your doctor may order an echocardiogram to:
    • Look for heart disease
    • Monitor heart valve disease over time
    • See how well medical or surgical treatments are working

    An electrocardiogram is a simple, painless test that measures your heart’s electrical activity. Every heartbeat is triggered by an electrical signal that starts at the top of your heart and travels to the bottom. Heart problems often affect the electrical activity of your heart.
