我院1981～1984年收治急性穿壁性心肌梗塞111例,现作一综合性回顾分析。本组111例病人的心电图,取住院期间变化最显著的一份作为ST段测量,按Niel-son标准,即下壁心肌梗塞ST段抬高≥2.0毫米,前壁心肌梗塞ST段抬高≥5.0毫米,作为ST段抬高组。在此标准以下者为非抬高组。按Morris测定法,检出住院期内,凡一次V_1导联P波终末电势(PTF)≤-0.04毫米·秒为异常。发病时心电图呈 Our hospital from 1981 to 1984 were treated 111 cases of acute transmural myocardial infarction, now make a comprehensive retrospective analysis. This group of 111 patients ECG, take the most significant change during hospitalization as ST segment measurement, according to Niel-son criteria, that ST-segment elevation of inferior wall myocardial infarction ≥ 2.0 mm, anterior ST-segment elevation myocardial infarction ≥ 5.0 mm as an ST-segment elevation group. The following standards in this non-lifting group. According to the Morris test, during the hospitalization period, the terminal potential of P wave (PTF) ≤-0.04 mm · s was abnormal in V_1 lead. When the onset of ECG was
