摘　　要：目的探讨应激性心肌病与急性前壁心肌梗死的心电图特征对比分析。方法方便选取该院2016年3月—2017年2月收治的60例应激性心肌病患者作为该次的研究对象,将其作为研究组,另选取同期参与研究的急性前壁心肌梗死患者作为对照组(60例),均对2组患者实施心电图检查,并对临床症状进行观察。结果该文研究中,应激性心肌病的病理性Q波发生率为15.00%,低于对照组(χ~2=24.36,P<0.05),T波倒置的发生率为30.00%,高于对照组(χ~2=9.09,P<0.05),无对应性改变情况,低于对照组(64.62,P<0.05);RR间期为(0.69±0.02)s,与对照组差异无统计学意义(t=2.24,P>0.05),QT间期为(0.44±0.06)s,高于对照组(t=5.95,P<0.05);且QTc为(0.56±0.04)s,QT离散度为(100.97±28.36)ms,高于对照组(t=14.52、7.95,P<0.05),V1~V3导联为(4.32±3.09),低于对照组(t=10.36,P<0.05),V4~V6导联为(6.10±4.25),与对照组差异无统计学意义(t=0.01,P>0.05),V4~V6/V1~V3为(1.52±0.52),高于对照组(t=10.00,P<0.05)。结论应激性心肌病与急性前壁心肌梗死具有一定的相似性,且临床表现特殊,临床中需予以慎重诊断。Objective To investigate the electrocardiographic features of stress-induced cardiomyopathy and acute anterior myocardial infarction.Methods 60 patients with stress-induced cardiomyopathy who were admitted to the hospital from March 2016 to February 2017 were selected as the study group.The patients were convenient selected as the study group.Patients with acute anterior myocardial infarction who participated in the study at the same time were selected as the study group.In the control group(60 patients),electrocardiogram was performed on both groups and clinical symptoms were observed.Results In this study,the incidence of pathologic Q waves in stress cardiomyopathy was 15.00%,which was lower than that of the control group,(χ2=24.36,P<0.05),and the incidence of T wave inversion was 30.00%,which was higher than that of the control group,(χ2=9.09,P<0.05),no change in correspondence,lower than the control group,(64.62,P<0.05);RR interval was(0.69±0.02)s,there was no significant difference with the control group(t=2.24,P>0.05),QT interval was(0.44±0.06)s,higher than the control group(t=5.95,P<0.05);and QTc was(0.56±0.04)s,and QT dispersion was(100.97±28.36)ms,higher than the control group(t=14.52,=7.95,P<0.05),V1 to V3 leads(4.32±3.09),lower than the control group,(t=10.36,P<0.05),V4 to V6 leads(6.10±4.25),no significant difference with the control group(t=0.01,P>0.05),V4 to V6/V1 to V3(1.52±0.52),higher than the control group(t=10.00,P<0.05).Conclusion There is a certain similarity between stress cardiomyopathy and acute anterior myocardial infarction,and the clinical manifestations are special.Therefore,it is necessary to make a careful diagnosis in clinical.
