摘　　要：目的对山区老年患者ST段抬高心肌梗死(STEMI)入院时心电图缺血程度(ST段抬高和QRS终末扭曲)再灌注溶栓治疗前后心电图进行临床分析。方法对108例心肌梗死患者分为2组,A组有QRS终末扭曲,B组无QRS终末扭曲;观察并记录溶栓治疗前后心电图变化及病死率。结果溶栓治疗前,有QRS终末扭曲比无QRS终末扭曲平均每个导联ST段抬高的程度明显,严重并发症室性心律失常多见。溶栓治疗后2 h,平均每个导联ST段下降的幅度均>50%,室性心律失常发生率比较差异无统计学意义;出院QRS扭曲梗死范围大、病死率高,无QRS扭曲组梗死范围小、病死率低(P<0.05)。结论山区老年患者ST段抬高心肌梗死入院时心电图有QRS终末扭曲缺血严重、梗死范围大、病程长病死率高,无QRS终末扭曲缺血轻、梗死范围小、病程短溶栓治疗后病死率低。Objective To analyze the degree of electrocardiogram(ECG)ischemia(ST elevation and QRS terminal distortion)before and after ST elevation myocardial infarction(STEMI)in elderly mountainous patients.Methods The 108 patients with myocardial infarction were divided into 2 groups:group A:QRS ter-minal distortion,group B:No QRS terminal distortion;ECG changes and mortality rate were observed before and after thrombolysis.Results Before thrombolysis,group A with QRS terminal distortion,the average degree of each guide ST section was significantly elevated,with more severely complicated ventricular arrhythmias.Two hours after bolus treatment,the flat decrease of each lead ST segment was greater than 50%,with no significant difference in ventricular arrhythmia;the QRS distortion infarction was high,and the incidence of QRS distortion was low(P<0.05).Conclusion Elderly patients in mountainous areas with ST-segment elevation myocardial in-farction on admission have QRS terminal distortion on the electrocardiogram,Severe ischemia,large infarct size,and long course of disease,No QRS terminal distortion,mild ischemia,small infarct size,short course of disease,and low mortality after thrombolytic therapy.
