| 摘 要： | 目的分析心电图aVR导联形态在阵发性室上性心动过速中的鉴别诊断价值。方法选取泰达国际心血管病医院行射频消融的室上性心动过速患者157例,男69例,女88例,年龄13~74岁,平均（41.9±19.2）岁,以心内电生理检查结果为金标准,分为慢快型房室结折返性心动过速组（SF-AVNRT组,n=89）和左侧房室旁路参与的房室折返性心动过速组（AVRT组,n=68）,入选者在窦性心律和室上性心动过速时无束支传导阻滞。结果与窦性心律时相比,SF-AVNRT组aVR导联QRS波终末部形态改变（假性r波或粗顿）的发生率73.0%,AVRT组aVR导联QRS波终末部形态改变（假性r波或粗顿）的发生率为1.5%,差异有统计学意义（P〈0.01）;与窦性心律时相比,SF-AVNRT组aVR导联ST段抬高、水平型移行或T波降支切迹的发生率为2.2%,AVRT组aVR导联ST段抬高、水平型移行或T波降支切迹的发生率为89.7%,差异有统计学意义（P〈0.05）。结论与窦性心律时相比,SF-AVNRT和AVRT在aVR导联具有不同的心电图特点,aVR导联QRS波终末部形态和ST段形态对判断室上性心动过速的类型具有重要意义,需高度重视aVR导联在室上性心动过速中的鉴别诊断价值。
