Why do I need a device change?
Cardiac pacemakers and implantable cardioverter defibrillators (also called CIEDs or cardiac implantable electronic devices) are used to correct abnormal heart rhythms. These devices are safe; however, there are times when the device needs to be replaced or changed. Your implanted device may need to be changed if:
- The battery voltage is depleted. The battery checks performed at your follow-up appointments will help your doctor determine when the battery in your device will need to be replaced.
- Your doctor determines you may benefit from a device with additional or more sophisticated features.
- The device has malfunctioned.
