Overview: An echocardiogram is a test that uses sound waves to make images of your heart. An echocardiogram (or echo) uses ultrasound to make images of your heart's chambers, valves, and walls, as well as the major blood vessels attached to the heart. Some of these images are continuous, like movies. This means that an echo can be used to see things like how the valves move while the heart is pumping. Modern echocardiogram machines also have the ability to use the Doppler effect. A familiar example of this effect is the difference in sound between a car moving toward you and one moving away from you. This technology allows your doctor to measure how blood moves in the different chambers and through the valves. It also allows your doctor to find obstructions in the blood flow. Echos can be used to identify many heart disorders, including HCM. The same basic technology is used in every other kind of medical ultrasound, including fetal ultrasounds.
