An Echocardiogram, often referred to in the medical community as a cardiac ultrasound or simply an Echo, is a sonogram of the heart. It uses standard ultrasound techniques to image twodimensional slices of the heart. The latest ultrasound system can produce 3-D real time image. High-frequency sound waves inaudible to the human ear are sent from the probe and directed towards the heart, part of which bounces back (echoes) to the probe and is interpreted by the ultrasound machine into images, blood flow within the beating heart. The images are than displayed on the monitor and recorded on disk for future review. This test is performed either by cardiac sonographers, cardiac physiologists or doctors trained in cardiology.1-3
