An artificial pacemaker is an electronic device placed under the chest skin to help the heart maintain a regular rhythm. The pacemaker system includes a pulse generator and electrical leads that connect the pulse generator to the heart.
Pulse generator – This small metal container contains a long life battery and the electrical circuitry that monitors your underlying heart rhythm. It regulates the rate of electrical pulses sent to your heart.
Leads – These flexible, insulated wires deliver the electrical impulses to your heart.
Most pacemakers work only when they are needed or upon demand. This means that the pacemaker sends out an impulse only when it senses that the heart has missed a beat or is beating too slowly. If the pacemaker senses no natural beat, it will pace continuously.
