Pacemaker

A pacemaker is a small device. It sends out mild electrical signals that keep your heart beating normally. The signals are painless. It can help stop the dizziness, fainting, and shortness of breath caused by a slow or unsteady heartbeat.

Pacemaker is powered by batteries. Most pacemakers are placed under the skin of your chest. They have thin wires, called leads. The leads pass through a vein into your heart. A pacemaker can help restore a normal heart rate. It is used when certain problems have damaged the heart’s electrical system, which normally keeps your heart beating steadily.
