permanent pacemaker
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. most pacemakers have wires (leads) that transmit electricity to the heart. a pacemaker has one or more leads. a lead goes from the pacemaker through the subclavian vein and into a heart chamber, such as the right atrium or right ventricle. the end of the lead is in the heart chamber to stimulate the muscle.
a permanent pacemaker is typically placed under the skin of the chest. one type of permanent pacemaker is placed inside the heart. this type does not have leads.
