Abstract

Implantable cardioverter defibrillators (ICDs) are being implanted in increasing numbers. At intraoperative defibrillation threshold tests refractory ventricular fibrillation (VF) requiring emergency open chest resuscitation is a major concern during implantation of nonthoracotomy ICD lead systems. A new method of high energy endocardial/extrathoracic defibrillation via the implanted ICD transvenous defibrillation electrode (TDE) was used to terminate refractory VF. During implantation of ICD with TDE in 20 patients refractory VF occurred in two patients. The arrhythmia was terminated with endocardial/extrathoracic defibrillation in both cases, and no complications were observed.

摘要

植入式心脏复律除颤器（ICD）的植入数量正在不断增加。在术中除颤阈值测试时，对于非开胸ICD导联系统植入过程中需要紧急开胸复苏的难治性室颤（VF）是一个主要问题。一种通过植入的ICD经静脉除颤电极（TDE）进行高能量心内膜/胸外除颤的新方法被用于终止难治性VF。在20例植入TDE的ICD患者中，有2例出现难治性VF。两例患者的心内膜/胸外除颤均终止了心律失常，且未观察到并发症。
