An echocardiogram (often called “echo”) is a graphic outline of the heart’s movement. During this test, high-frequency sound waves, called ultrasound, provide pictures of the heart’s valves and chambers. This allows the technician, called a sonographer, to evaluate the pumping action of the heart.
Transthoracic echocardiogram: This is the standard echocardiogram. Using a device called a transducer, high frequency sound waves (ultrasound) are bounced off the heart structures, producing images and sounds that can be used by the doctor to detect heart damage and disease. Echo is often combined with Doppler ultrasound and color Doppler to evaluate blood flow across the heart’s valves.
