摘要 目的 分析阿托品作为诱导剂对房室结双径路(DAVNP)的电生理影响及其在心房调搏术(TEAP)中对房室结折返性心动过速(AVNRT)的诱发结果.方法 以阵发性心悸就诊行TEAP诊断为DAVNP但未诱发AVNRT并无阿托品禁忌的患者32例为研究对象,予阿托品静脉注射后重复TEAP并记录检查结果.结果 RR间期较前缩短(P<0.01),房室传导的文氏点较前推后(P<0.01),快、慢径路ERP及二者差均较前缩短(P<0.01),快、慢径路CT均较前缩短(P<0.01),S2R间期跳跃值较前缩短(P<0.01),心房ERP较前缩短(P<0.05).用药后13例患者不再出现跳跃文氏.用药后12例诱发AVNRT,2例诱发单个或成对房室结折返激动,2例诱发单个心房回波.结论 应用阿托品后部分患者不再出现DAVNP的征象,但可使50%患者诱发AVNRT、单个或成对房室结折返激动或心房回波.
