An echocardiogram is an ultrasound test that checks the structure and function of your heart. An echo can diagnose a range of conditions including cardiomyopathy and valve disease.
An echocardiogram (echo) is a graphic outline of your heart’s movement. During an echo test, your healthcare provider uses ultrasound (high-frequency sound waves) from a hand-held wand placed on your chest to take pictures of your heart’s valves and chambers. This helps the provider evaluate the pumping action of your heart.
Providers often combine echo with Doppler ultrasound and color Doppler techniques to evaluate blood flow across your heart’s valves.
Echocardiography uses no radiation. This makes an echo different from other tests like X-rays and CT scans that use small amounts of radiation.
