Folie à deux: an old diagnosis with a new technology.

The implantable cardioverter defibrillator (ICD) is the treatment of choice for life-threatening ventricular tachyarrhythmias. Despite this, indications for explantation have been described. Psychiatric complications have been considered in the decision to not re-implant a previously explanted device but never as a primary indication for explantation. The case of a woman who requested ICD explantation amidst concerns that the titanium used in its construction was absorbing harmful negative electromagnetic field energy from the environment resulting in intermittent bouts of fatigue, diaphoresis and an overall sense of impending doom is presented. She and her husband had significant psychosocial impairment because of this belief system. The present case is the first known report of a psychiatric complication as the primary indication for ICD explantation. It is illustrative of diagnostic dilemmas, competency and the importance of quality of life.
