Unfortunately Fortunate: Self-Terminating Device-Initiated Tachyarrhythmia in a Patient With a History of Idiopathic
1Department of Cardiology, Brooke Army Medical Center, San Antonio, Texas, Uniformed Health Services Consortium, San Antonio, Texas.
Abstract:
An 88-year-old female presented with inappropriate implantable cardioverter-defibrillator shocks. Interrogation revealed lead noise sensed as ventricular fibrillation, leading to 11 shocks in 1 day. A defibrillation at the period of maximal vulnerability caused true ventricular fibrillation/ventricular tachycardia and additional shocks, which failed to terminate device-initiated tachyarrhythmia. The patient recovered spontaneously and the device was reprogrammed. (Level of Difficulty: Intermediate.).
