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