摘要
目的 探讨植入型心律转复除颤器(ICD)及心脏再同步化心律转复除颤器(CRT-D)除颤电极导线功能故障的发生率、可能原因及处理方法.方法 对166例植入ICD或CRT-D的患者进行长期跟踪随访,统计除颤电极导线功能故障发生率,分析其可能原因及处理方法.结果 166例患者中出现除颤电极导线功能故障5例,发生率为3.01%.其中电极导线绝缘层破裂1例,ICD导线功能障碍1例,R波感知逐渐降低3例.其中2例予以更换除颤电极导线,2例予以植入普通主动固定电极导线,余1例随访中待择期处理.结论 植入ICD或CRT-D的患者,除颤电极导线功能障碍可引起ICD不适当放电,随访中若发现除颤电极导线功能障碍,应及时更换导线.
Objective To examine the incidence, causes, and management of defibrillation leads failure of implanted cardiac defibrillators (ICD) and cardiac resynchronization therapy plus defibrillator (CRT-D) devices. Methods One hundred and sixty-six patients with implanted ICD or CRT-D were followed up. Results Five out of 166 patients presented defibrillation lead failure with a incidence rate of 3.01%. Among 5 cases 1 had insulation defects, 1 had lead functional failure and 3 had T-wave suppression feature. New defibrillation lead was implanted in 2 patients and active-fixation pacing lead was implanted in another 2 patients. Conclusion Defibrillator lead failure can cause inappropriate shocks. It can be prevented by implantation of new defibrillator lead.
