An Echocardiogram is a procedure that sends ultrasound waves (like sonar) into the chest to create moving pictures of the heart. You may only think of ultrasound being used to monitor a baby’s growth, but ultrasound waves can also show the size of the heart’s chambers and how well they are working. This simple, painless test often provides valuable information about damage to a heart and also helps gather information about a heart with irregular beats (arrhythmia).
