The heart is a pump made up of muscle. The muscle is stimulated by electrical signals. These signals normally follow a specific circuit within the heart. These signals organize contractions of the different parts of the heart. This makes it beat at a rate that keeps blood flowing around the body the way it should. A pacemaker may be needed when there are problems with the electrical signals in the heart. Your heart may sometimes beat too slowly, or at an irregular rate.
A pacemaker is made of 3 parts. They include a pulse generator, 1 or more leads, and an electrode on each lead. A pacemaker signals the heart to beat when the natural heartbeat is too slow or irregular.
