Benefits and Risks – Implantable Cardioverter Defibrillators

Tachycardia (Fast Heartbeat)

Living with heart disease can be frightening. For some, it means being at risk for dangerously fast and potentially life-threatening heart rates. Fortunately, an implantable cardioverter defibrillator (ICD) can provide protection and life-saving therapy, giving you greater peace of mind.


An ICD is designed to treat dangerously fast heart rates. It continuously monitors your heart and restores your heart to its normal heart rate. It’s like having an emergency response team with you 24 hours a day, 7 days a week.


Risks associated with an ICD implant include, but are not limited to, infection at the surgical site and/or sensitivity to the device material, failure to deliver therapy when it is needed, or receiving extra therapy when it is not needed.

After receiving an ICD, you will have limitations with respect to magnetic and electromagnetic radiation, electric or gas-powered appliances, and tools with which you are allowed to be in contact.

Treatment with an ICD is prescribed by your doctor. This treatment is not for everyone. Please talk to your doctor to see if it is right for you.

Your doctor should discuss all potential benefits and risks with you. Although many individuals benefit from the use of this treatment, results may vary.
