摘要 目的探讨心电图判断冠状动脉多支病变的价值。方法回顾性分析192例冠心病的心电图与冠状动脉造影(CAG)资料。根据CAG确定病变范围,以心电图Ⅲ导联、Ⅱ导联、aVL导联低电压(依次为指标A、指标B、指标C),电轴左偏(指标D)、V5和V6导联ST改变(指标E)及合并心律失常(指标F)作为判别标准。结果192例病人中,单支病变74例,双支病变65例,多支病变53例;各指标识别多支病变的敏感性和特异性分别为30.19%、83.45%;15.09%、85.61%;22.64%、80.58%;52.83%、67.63%;71.70%、60.43%;28.30%、84.89%。V5和V6导联ST的敏感性最高,Ⅱ导联低电压的特异性最高,合并心律失常的准确性最高。结论心电图改变有助于初步判别冠心病的多支病变。
