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.
一位 75 岁男性，患有非缺血性心肌病，植入了双心室植入式心脏除颤器（ICD）。间歇性 T 波过感知（TWOS）限制了双心室起搏的一致性。采用左心室单独起搏策略来消除 TWOS。这种策略避免了降低心室敏感性的需要，因此可能是 TWOS 复杂的双心室起搏的有效替代方法。
