Pacemaker Application

¿What is a Pacemaker?

A healthy heart has its own Pacemaker to regulates the rate of the heartbeats.

However, some hearts don't beat regularly, and a Pacemaker can correct the issue. 


A Pacemaker is a little battery-operated device that sends electrical impulses to the heart and maintains a proper heart rate and rhythm. 


Some of the main characteristics of Pacemakers are:

  • It's inserted under the skin of the chest during minor surgery

  • The Pacemaker has two parts: a generator and wires

  • The generator is a small battery-powered unit

  • The generator is plug to your heart through tiny wires

  • Some Pacemakers are external and not surgically implanted


¿How do Pacemakers work?

  • The Pacemaker replaces the heart's inadequate natural Pacemaker functions

  • The sinoatrial node is the heart's original Pacemaker. It produces the electrical impulses that make your heartbeat

  • The chamber of the heart contracts when an electrical impulse moves across it

  • The Pacemaker's pulse generator sends an electrical impulse to the heart to help it beat properly. A tiny electrode placed next to the heart wall is the one who makes this task
