摘要:
 【摘要】 目的 了解移行于V3导联流出道室性早搏(室早)心电图和三维激动标测图临床特点。方法 回顾行分析17例流出道室早患者,根据消融结果分为右室流出道(RVOT)(间隔)组,左室流出道(LVOT)组,比较两组心电图和三维激动标测图特点。结果 心电图,V2导联R波时间指数RVOT(间隔)与LVOT起源室早比较[0.32(0.23 ~ 0.42)比0.48(0.39 ~ 0.5)], 差异有统计学意义(P < 0.05)。三维激动标测图,10 m内激动区域RVOT(间隔)面积和周长明显小于LVOT[面积:1.2(0.5 ~ 2.2)比3.3(2.3 ~ 3.8),P < 0.05],[周长4.3(2.8 ~ 5.8)比7.9(7 ~ 9.5),P < 0.05];且10 m内激动区域RVOT(间隔)呈纵轴大于横轴,与LVOT长轴/短轴比例[1.04(0.96 ~ 1.12)比0.49(0.42 ~ 0.56),P < 0.05]。结论 对于移行于V3导联流出道室早,心电图V2导联R波时间指数与三维激动标测图10 ms 激动区域形状,面积,周长均有助于于判断位置起源。
