Pacemaker Implant

A pacemaker is a small lightweight electronic device that is prescribed for people whose heart is beating too slowly. It is implanted into the body, usually in the upper chest, near the shoulder.

The pacemaker keeps track of the heart’s electrical activity. If it senses that the heart is beating too slowly or is pausing too long between beats, the pacemaker delivers electrical impulses that pace the heart and keeps it beating at the proper speed.

If your heart rhythm is too slow, this may cause symptoms such as lightheadedness, fainting, and tiredness. A pacemaker gives your heart the extra help it needs to relieve your symptoms and help you feel better. Also, having a pacemaker can give you more freedom to do the activities you enjoy.

Your doctor may recommend a pacemaker if you have one or more of the following conditions:

  • bradycardia with significant symptoms, such as dizziness, fainting spells, tiredness, confusion, or shortness of breath
  • bradycardia with a very slow heart rate or long pauses between beats, even without symptoms
  • arrhythmias where the heart alternates between beating too fast and too slowly
  • arrhythmias and other medical conditions that require medications that cause bradycardia
  • recurring syncope that is caused, at least in part, by significant slowing of the heartbeat
  • severe bradycardia caused by heart surgery or catheter ablation
