摘　　要：植入型心律转复除颤器的右室除颤电极导线通常放置于右室心尖部,但近来研究显示长期右室心尖部起搏会导致心脏收缩和舒张功能下降,另外,当右室心尖部起搏阈值和/或除颤阈值较高时,需改变除颤电极导线的放置位置,以达到最佳的治疗效果。相对于右室心尖部而言,右室流出道放置除颤电极导线有一定的优势。现对右室流出道放置除颤电极导线的相关问题做一简要的综述。The right ventricular implantable cardioverter defibrillator lead is a standard treatment that is placed in the right ventricular apex. However, patients who are paced in the right ventricular apex may develop pacing-induced left ventricular systolic and diastolic dysfunction. In addition, when the pacing threshold and/or the defibrillation threshold is high in the right ventricular apex, the position of the cardioverter defibrillator lead needs to be changed in order to achieve the best therapeutic efficacy. Compared with right ventricular apex, the placement of the implantable cardioverter defibrillator lead in the right ventriGular outflow tract has advantages. This article discusses the relative problems of the placement of the right ventricular implantable cardioverter defibrillator lead in the right ventricular outflow tract.
