摘要(Abstract)：

目的 探讨左后间隔基底部起源的室性心律失常（VAs）体表心电图特点及三维标测指导下射频消融治疗的效果。方法 回顾性分析2018年12月至2021年1月在首都医科大学附属北京安贞医院住院的 连续6例起源于左 后间隔基底部的VAs患者。所有患者均在三维标测系统指导下进行激动标测，并行射频消融治疗，分析患者12导联心电图QRS波特征。结果 6例VAs患者经射频消融全部即刻成功，随访复发1例（1/6），该病例左心室及右心标测后最早激动点位于左后间隔基底部，多次消融后室 性期前收缩消失。所有患者均无并发症发生。起源于左后间隔基底部的VAs患者心电图特征均表现为完全性右束支传导阻滞，电轴左偏，Ⅰ、aVL导联呈高大的R型，Ⅱ导联呈r S型，Ⅲ、aVF导联呈r S型或QS型，V_1导联呈r’s R型或R型，V_2～V_4导联呈高大R型，V_5导联呈Rs型或R型，V_6导联呈Rs型，R/s>2。结论 左后间隔基底部起源的VAs患者有典型心电图特征，三维标测系统指导射频消融治疗该部位起源的VAs安全有效。由于解剖结构的影响，部分患者需要使用普通盐水灌注导管到位消融。
