This type of echo involves placing a device called a transducer on your chest. The device sends special sound waves, called ultrasound, through your chest wall to your heart. The human ear can't hear ultrasound waves. As the ultrasound waves bounce off the structures of your heart, a computer in the ECHO machine converts them into pictures on a screen.
