What is a pacemaker?

If you have a condition called bradycardia, otherwise known as a slow heartbeat, you and your doctor may decide an implantable heart device called a pacemaker is the right option for you.

When people refer to a pacemaker, they are actually discussing a pacing system, which includes the pacemaker and leads.

  • A pacemaker is the small device that is implanted under the skin, most often below the collarbone on the left or right side of your chest. The pacemaker continuously monitors your heart, and if it detects a slow heart rate, it sends out small undetectable electrical signals to correct it.
  • Leads are thin, soft, insulated wires about the size of spaghetti noodles. The leads carry the electrical impulse from the pacemaker to your heart and relay information about the heart’s natural activity back to your pacemaker.
