摘要(Abstract)：

目的研究急性下壁心肌梗死心电图某些特点对合并冠状动脉多支病变的判断价值。方法分析236例首次发生急性下壁心肌梗死患者的某些心电图的特征改变,与其入院时的冠状动脉造影(CAG)资料进行对比。结果急性下壁心肌梗死心电图伴下列1项或以上患者对预测合并冠状动脉多支病变有较高的敏感性和特异性:(1)伴STV4~V6↓;(2)伴STⅡ、Ⅲ、a VF↑>0.2 m V+STa VR↑;(3)伴a VF导联低电压;(4)伴2个或以上胸前导联f QRS波;(5)伴STV4R↑+STa VL↓/STⅠ↓<1。其中急性下壁心肌梗死心电图伴STV4~V6↓时对判定患者合并冠状动脉多支病变有较高的敏感性和特异性。结论急性下壁心肌梗死心电图某些特征的改变对判定患者合并冠状动脉多支病变有较好的临床应用价值。
