    What is an Echocardiogram?

    An echocardiogram (also called an "echo"), is a non-invasive test to look at the structure and motion of heart function, heart valves, and blood flow through the heart. This test uses ultrasound (high-frequency sound waves) to create an image of your heart on a television screen (monitor). A specially trained cardiac sonographer does the test. This test takes 45-50 minutes.

    Note: There is no proven risk of exposure to humans from this test.

    During Your Test

    • When you are comfortable on the table, the sonographer applies electrodes (small pads) to your chest to monitor your heartbeat. Then, the sonographer applies gel to your chest area.


    • The sonographer places a transducer (a wand-like object) on your chest and takes several images of your heart. You may feel pressure during the test as the sonographer presses down to get clear images.


    • The staff may use a contrast agent (liquefied gas) during the test to get a better image of your heart.


    • The nurse places an intravenous line (IV) in your hand or arm.


    • The sonographer takes additional images of the heart after the contrast agent is injected. The nurse removes the IV at the end of the procedure.
