Strategy to eliminate inappropriate shocks secondary to T-wave oversensing in a biventricular ICD

Abstract

T-wave oversensing represents a common cause of inappropriate shocks in patients with implanted cardiac defibrillators. This case report demonstrates a strategy of device programming using V-V pace delay (sequential rather than simultaneous biventricular pacing) to eliminate T-wave oversensing without decreasing sensitivity to detect true tachyarrhythmia. © 2009, The Authors.
