An echocardiogram (echo) is a test that uses high frequency sound waves (ultrasound) to make pictures of your heart. The test is also called echocardiography or diagnostic cardiac ultrasound.

  • An echo uses sound waves to create pictures of your heart’s chambers, valves, walls and the blood vessels (aorta, arteries, veins) attached to your heart.
  • A probe called a transducer is passed over your chest. The probe produces sound waves that bounce off your heart and “echo” back to the probe. These waves are changed into pictures viewed on a video monitor.
  • An echo can’t harm you.

The test helps your doctor find out:

  • The size and shape of your heart, and the size, thickness and movement of your heart’s walls.
  • How your heart moves.
  • The heart’s pumping strength.
  • If the heart valves are working correctly.
  • If blood is leaking backwards through your heart valves (regurgitation).
  • If the heart valves are too narrow (stenosis).
  • If there is a tumor or infectious growth around your heart valves.

The test also will help your doctor find out if there are:

  • Problems with the outer lining of your heart (the pericardium).
  • Problems with the large blood vessels that enter and leave the heart.
  • Blood clots in the chambers of your heart.
  • Abnormal holes between the chambers of the heart.

An echo doesn’t hurt and has no side effects.
