Keyword:  心动过速室上性心电描记术食管心电图12导联同步心电图;
Abstract: 目的:探讨食管心电图结合12导联同步心电图在折返性室上性心动过速诊断中的作用.方法:75例有心悸史的患者记录心动过速时12导联同步心电图,食管心电图以及心内电生理检查结果.结果:在食管心电图合并12导联心电图中RP'≤70 ms的患者,诊断为房室结折返性心动过速,经心内电生理检查证实特异性为100%,敏感性为97.33%.70 ms140ms的患者,诊断为房室折返性心动过速伴右侧旁路,经心内电生理检查证实特异性为100%,敏感性为100%.结论:测量折返性室上性心动过速食管心电图和12导联同步心电图的RP'间期,可以鉴别房室结折返性心动过速和房室折返性心动过速,并预测旁路定位.
