Description of Test
A gel is put on your chest. This gel helps the sound waves travel. A small, hand-held device called a transducer is pressed against your skin. The transducer sends sound waves toward your heart. The sound waves are then reflected back to the device. The waves are converted into electrical impulses. These impulses become an image on the screen.
Still images or videotape moving images can be captured. To get clearer and more complete images, the transducer may be moved to different areas of your chest. You may be asked to change positions and slowly inhale, exhale, or hold your breath.
The gel is wiped from your chest.
