Implantable Cardioverter - Defibrillators

Implantable cardioverter Defibrillators (ICDs) are small electronic devices implanted to treat dangerously fast heartbeats that can lead to sudden cardiac arrest, in which the heart stops pumping blood.  ICD's are typically about the size of a phone pager with long lasting durable batteries. Replacing an ICD can be done as an outpatient procedure, and restrictions following surgery are not as stringent as with the initial implant. They are implanted under the skin of your chest, near the left collarbone, with wires running to the heart.

Implantable cardioverter Defibrillators monitor and deliver electrical shocks to the heart as necessary to eliminate abnormal rhythms. For a heartbeat that is too slow, they work as a pacemaker and sends electric signals to the heart. For a heartbeat that is too fast, it sends defibrillation shocks to stop the abnormal rhythm. These devices work 24 hours a day 7 days a week and are individually programmed. ICDs can also be programmed using radio waves so that they can be adjusted externally. There are approximately 250,000 to 270,000 patients in the United States have implantable defibrillators. Please contact your physician for further information on whether you qualify as a candidate for an ICD.

If you or someone you know has an Implantable Cardioverter Defibrillators, here are some general health safety guidelines:
  • Always consult your physician prior to any strenuous activities and visit your physician on a regular basis.

  • If you travel by air inform the security forces prior to being scanned by any hand held security scanners.

  • Avoid any strong magnetic fields including any concentration of magnets.

  • Communicate with and inform all medical personal about your condition, verbally and with an ID card letting others know that you have an implantable defibrillator.
