Despite their similarity to permanent pacemaker leads, endocardial sensing leads for cardioverter defibrillators have a relatively high failure rate. We describe four patients with endocardial rate sensing leads who developed inappropriate discharges 10-30 months after implantation due to small breaks in the lead insulation. This problem may become increasingly common as the number of cardioverter defibrillator implants with transvenous leads continues to grow and should be considered in the differential diagnosis of late sensing failure or inappropriate device discharges.
尽管心内膜感知电极导线与永久性起搏器导线相似，但用于心脏转复除颤器的心内膜感知电极导线故障率相对较高。我们描述了4例植入心内膜心率感知电极导线的患者，他们在植入后10 - 30个月因导线绝缘层出现小破损而发生不适当放电。随着经静脉导线植入心脏转复除颤器的数量持续增加，这个问题可能会变得越来越普遍，在晚期感知失败或设备不适当放电的鉴别诊断中应予以考虑。
