Echo-cardiogram (ECHO)

An echo-cardiogram (ECHO) is a graphic outline of the heart’s movement. During an echo test, ultrasound (high-frequency sound waves) from a hand-held wand placed on your chest provides pictures of the heart’s valves and chambers and helps the sonographer evaluate the pumping action of the heart. Echo is often combined with Doppler ultrasound and colour Doppler to evaluate blood flow across the heart’s valves.
