What happens during an echocardiogram?

ANSWER

A cardiac sonographer will place three electrodes (small, flat, sticky patches) on your chest. The electrodes are attached to an electrocardiograph monitor that charts your heart's electrical activity.

The sonographer will ask you to lie on your left side on an exam table. They will place a wand (called a sound-wave transducer) on several areas of your chest.

You may be asked to change positions several times during the exam. You may also be asked to hold your breath at times.
