• Pacemakers are implants that are put in the heart to help manage the rate of your heartbeat.
  • After a heart attack, surgery, or a medicine overdose, they can be temporarily implanted to treat a weak heartbeat.
  • They can be permanently implanted to correct a slow or irregular pulse or, in some cases, to assist in the treatment of heart failure.
