Pacemakers and implantable cardiac defibrillators in dermatologic surgery.

Background: Electrosurgery used during dermatologic surgical procedures can cause malfunction of pacemakers and implantable cardiac defibrillators (ICDs), producing problems with rhythm detection, proper function, or alteration of the device. Well-documented safety data on electrosurgery in patients with cardiac devices are limited. At Mayo Clinic in Rochester, Minnesota, the Pacemaker Clinic manages all patients with pacemakers and ICDs undergoing dermatologic surgery.
