A pacemaker is a small device that is used to regulate your heart rhythm. A pacemaker system is a two part electrical system comprised of a pulse generator and either one or two leads.
The pulse generator is a small implantable device that is approximately the size of four stacked half dollar coins. Inside its metal shell, the pulse generator contains the electronic circuitry, which continuously analyzes the heart's rhythm and regulates the pacemaker function, as well as a lithium battery that provides the power source for the device.
The leads are thin insulated wires that are implanted inside the heart muscle in either the right atria, the right ventricle, or in both chambers. The leads receive electrical information from the heart (sensing) as well as transmit electrical impulses to the heart to stimulate it to beat (packing).
