Transthoracic Echocardiogram

Test Overview

An echocardiogram (also called an echo) uses sound waves to make an image of your heart. A device called a transducer sends sound waves that echo off your heart and back to the transducer. These echoes are turned into moving pictures of your heart that can be seen on a video screen.

In a transthoracic echocardiogram (TTE), the transducer is moved across your chest or belly. A TTE is the most common type of echocardiogram.
