Ventricular fibrillation initiated by an electrocution injury and terminated by an implantable cardioverter-defibrillator.

A 52-year-old man with an implantable cardioverter-defibrillator (ICD) was accidentally electrocuted when a flagpole he was erecting contacted an overhead electrical power line. The electrocution injury initiated ventricular fibrillation. The ICD sensed the arrhythmia and delivered therapy, converting his rhythm to sinus rhythm. The patient had no subsequent cardiac or neurological sequelae.
