An echocardiogram (also called an Echo) is a type of ultrasound test that uses high frequency sound waves that are sent through a device called a transducer.  The device picks up echoes of the sound waves as they bounce off the different parts of your heart.  These echoes are turned into moving pictures of your heart that can be seen on a video screen.  Views of the heart are obtained by moving the transducer to different locations on your chest or abdominal wall.

Preparation:  No preparation is required.
