What are artificial pacemakers?
An artificial pacemaker stimulates a programmed and appropriate heartbeat in patients who have a slow heart rate. The pacer is a device that is made up of a battery-powered generator that sends signals to the heart through wires that are connected to the heart . The pacer senses heartbeats and fires a stimulus back to the heart if the beats that it senses do not come at the appropriate time. A pacemaker therefore detects heartbeats that are too slow or irregular and provides electrical signals that tell the heart to beat at a proper rate by delivering signals to the appropriate chambers of the heart.
