An echocardiogram (echo) is a test that uses ultrasound to make pictures of your heart. Your doctor may use an echo test to look at your heart’s structure and check how well your heart functions. This test can help show your doctor:
- The size and shape of your heart, and the size, thickness and movement of your heart’s walls..
- The heart’s pumping strength.
- If the heart valves are working correctly.
- If there is a tumor or infectious growth around your heart valves.
