(HealthDay News) - A pacemaker is a small, battery-powered device that is implanted in the skin of the chest or abdomen, and helps regulate the heartbeat.

Here are reasons for why a pacemaker may be prescribed, courtesy of the U.S. National Heart, Lung, and Blood Institute:

To correct a slow, fast or irregular heartbeat.
To ensure that the heart's ventricles contract normally, in cases of atrial fibrillation.
To regulate the electrical signals between the upper and lower chambers of the heart, and in other cases, between the ventricles of the heart.
