<正>患者男,60岁。因“活动后心慌胸闷1月余”就诊,行心电图检查提示三度房室阻滞,心率41次/分。外院动态心电图可见较多阵发性房扑。患者为寻求植入无导线房室同步起搏器(Micra AV
MC1AVR1
美敦力)来我院。治疗策略为:先进行Micra AV植入,若房扑发作频繁,择期行房扑经导管射频消融术(RFCA)。患者于2020年12月11日置入Micra AV无导线起搏器。植入过程:患者平卧位,局麻下穿刺右股静脉,逐步扩张股静脉,送入27F传送鞘管,经传送鞘管送入无导线起搏器递送系统,左前斜和右前斜下给予造影证实起搏器鞘管顶住右心室中上间隔面,打鹅颈弯,释放起搏器(图1),牵拉试验可见起搏器4个固定小翼张合变化,测试参数良好,
