埋藏式心脏转复除颤器(ICD)导线故障的原因有导线与机体的相互作用、植入技术欠佳和导线本身的缺陷。临床表现为起搏感知功能异常、除颤功能异常及机械并发症。可通过起搏与感知功能表现以及阻抗的变化加以识别,通过铁磁试验以及更换或拔除导线进行相应处理。 Buried cardioverter defibrillator (ICD) wire failure causes of the wire and the body interaction, poor implant technology and the wire itself defects. Clinical manifestations of paresthesia dysfunction, defibrillation dysfunction and mechanical complications. It can be identified by pacing and sensing of functional performance and changes in impedance, handled by ferromagnetic testing and by replacement or removal of leads.
