Pacemaker

A pacemaker is a small, battery-operated electronic device which is inserted under the skin to help the heart beat regularly and at an appropriate rate. The pacemaker has leads that travel through a large vein to the heart, where the wires are anchored. The leads send the electrical impulses to the heart to tell it to beat.
