摘要 目的探讨急性左主干闭塞心肌梗死的心电图特点及护理措施。方法回顾分析发病12h内经冠状动脉造影诊断为左主干及前降支、回旋支、右冠状动脉近端病变的急性ST段抬高心肌梗死患者入院时的心电图。护理方法包括减少心肌耗氧,增加心肌氧供,密切观察病情变化等。结果II、III、aVF导联ST段压低、aVR与aVL导联ST段抬高、aVR导联ST段抬高较V1导联明显等在左主干组均较其他各组更常见(P<0.05)。aVR导联ST段抬高的发生率在左主干组高于其余各组,与前降支组相比差异无统计学意义(P>0.05)。II、III、aVF导联ST段压低预测左主干闭塞敏感性64%,aVR与aVL导联ST段同时抬高特异性98%。结论II、III、aVF导联ST段压低及aVR、aVL导联ST段同时抬高有助于临床早期识别左主干急性闭塞。有效的护理可以辅助提高疗效,改善预后。
