Using Left-Ventricular-Only Pacing to Eliminate T-Wave Oversensing in a Biventricular Implantable Cardiac Defibrillator

摘要

A man aged 75 years and with nonischemic cardiomyopathy had implantation of a biventricular implantable cardiac defibrillator (ICD). Consistent biventricular pacing was limited by intermittent T-wave oversensing (TWOS). A strategy of left-ventricular-only pacing was used to eliminate TWOS. This strategy obviates the need to reduce ventricular sensitivity and thus may be an effective alternative to biventricular pacing complicated by TWOS. ? 2013 Canadian Cardiovascular Society.
