Fatal outcome from inappropriate defibrillation

Europace. 2007 Nov;9(11):1059-60. doi: 10.1093/europace/eum186. Epub 2007 Sep 6.

Abstract

We present a 51-year-old morbidly obese man who underwent insertion of a single-chamber implantable cardioverter defibrillator for monomorphic ventricular tachycardia occurring after myocardial infarction. After a period of satisfactory device function, a sudden change in R-wave with atrial over-sensing heralded inappropriate defibrillation and induction of ventricular fibrillation, with subsequent death of the patient.
