Answer

Cardioversion of patients with implanted pacemakers and defibrillator devices is safe when appropriate precautions are taken. Keeping the cardioversion pads in an AP orientation ensures that the shocks are not directly over the generator. Alteration in pacer-programmed data has been reported, as well as heart block and elevated enzymes if the current is conducted through a pacer lead.
