- Artificial cardiac pacemaker.

Artificial cardiac pacemaker.

It is a medical device that uses electrical impulses, delivered by electrodes contacting the heart muscles, to regulate the beating of the heart so it mimics the action of your natural pacemaker..

Pacemakers can be temporary (here) or permanent.

Pacemaker consists of two parts:
  1. The pulse generator: This small metal container houses a battery and the electrical circuitry that regulates the rate of electrical pulses sent to your heart.
  2.  Leads: These flexible, insulated wires deliver the electrical pulses to your heart.
Pacemakers monitor your heartbeat and, if it's too slow, the pacemaker will speed up your heart rate by sending electrical signals to your heart. In addition, most pacemakers have sensors that detect body motion or breathing rate, which signals the pacemaker to increase your heart rate during exercise to meet your body's increased need for blood and oxygen.
