An echocardiogram is a type of ultrasound test which produces images of the heart valves and heart muscles. This test assists the doctor to examine the proper function of the heart by recording the heart beats. The images produced by the echocardiogram are live and can be further used to detect any heart abnormalities in the heart valves and muscles. Also, the quality of the pictures produced by this test is more enhanced than the X-ray. Echocardiogram also helps in recording the pumping of the heart. Echocardiogram or Echo, when used with Doppler ultrasound and color doppler assists in monitoring the blood flow carefully across the valves of the heart. An echocardiogram is a very safe and painless procedure as it does not exposes the patient to any kind of harmful radiations. Instead, it uses sound waves to create images of various structures of the heart with the help of a small probe called transducer.
