摘要 目的分析急性心肌梗死心电图中缺血性J波与恶性室性心律失常的关系,评价缺血性J波预测急性心肌梗死后发生恶性室性心律失常的临床价值。方法将96例ST段抬高型急性心肌梗死患者按梗死后心电图检查是否记录到缺血性J波分为J波组37例与非J波组59例,比较2组急性心肌梗死部位及梗死后发生恶性室性心律失常的情况。结果 J波组2个及以上部位心肌梗死发生率显著高于非J波组(51.3%比8.5%,χ2=10.978,P=0.027),且恶性室性心律失常发生率也显著高于非J波组(48.6%比6.8%,χ2=13.069,P=0.011)。结论心电图缺血性J波可作为急性心肌梗死发生恶性室性心律失常的预警指标,且可提示心肌梗死范围较大。
