The pacemaker is a small metal box weighing 20-50g, which is attached to one or more pacing leads (wires) that run to your heart. The pacemaker contains:
· a battery (which usually lasts 6 to 10 years),
· a pulse generator, and
· a tiny computer circuit that converts energy from the battery into electrical impulses, which flow down the wires and stimulate your heart to contract.
The rate at which these electrical impulses are sent out is called the discharge rate.
