The test is also called echocardiography or diagnostic cardiac ultrasound.
Quick facts. 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.
An echocardiogram, or “echo”, is a scan used to look at the heart and nearby blood vessels.
It’s a type of ultrasound scan, which means a small probe is used to send out high-frequency sound waves that create echoes when they bounce off different parts of the body.
