| 摘 要： | 目的：探讨体表心电图(ECG)对 ST 段抬高性急性下壁心肌梗死(IAMI)患者梗死相关动脉及闭塞部位的预测价值。方法选择 ST 段抬高性 IAMI 患者95例,记录入院时18导联 ECG,并行急诊经皮冠状动脉介入治疗,按照冠状动脉造影(CAG)结果进行分析。结果 ST Ⅲ抬高>STⅡ预测右冠状动脉(RCA)闭塞的敏感度和特异度分别为93.4%、73.7%；ST V3/Ⅲ≤1.2、ST aVL 下移>STⅠ预测 RCA 闭塞的敏感度分别为88.2%和92.1%；而 ST V3R-V5R 抬高判断 RCA 闭塞的特异度为100%；ST V3/Ⅲ<0.5预测 RCA 近段闭塞的敏感度为86.7%；ST V4R 抬高判断 RCA 近段闭塞的特异度为93.5%,ST Ⅲ抬高≤ STⅡ判断左回旋支(LCX)闭塞的敏感度和特异度分别为73.7%和93.4%,ST V2压低>0.15 mV 预测 LCX 近段闭塞的敏感度为87.5%。结论体表心电图Ⅲ、V3、V4R、aVL 导联 ST 段改变对预测 RCA 闭塞有价值,而 ST V2压低有助于预测 LCX 闭塞。
