Permanent Pacemaker

Picture of a permanent pacemaker and where it is placed

A pacemaker is a small, battery-powered device that sends out small electrical impulses to make the heart beat in a regular rhythm and at a normal speed. A pacemaker consists of a pulse generator and battery that create the electrical impulses, and wires (leads) that transmit electricity to the heart.

A permanent pacemaker is typically placed under the skin of the chest.
