心电图异常J波预测急性ST段抬高型心肌梗
探讨急性ST段抬高型心肌梗死(ASTEMI)患者心电图异常J波与住院期间预后的关系。
ToexploretherelationshipbetweenabnormalECGJwaveandin-hospitalprognosisinpatientswithacuteST-segmentelevationmyocardialinfarction(ASTEMI).回顾性分析年1月至年12月在我院行急诊冠脉介入治疗(PCI)的例ASTEMI患者心电图及相关临床资料,根据有无异常J波,分为异常J波组(82例,占40.2%,82/)和无异常J波组(例,占59.8%,/),应用单因素、多因素Logistic回归分析患者住院期间死亡的危险因素。
