近年来急性下壁心肌梗塞并胸前对应导联ST段下降越来越引起人们的重视。本文总结了我院1968~1988二十年间住院的急性下壁心肌梗塞124例,旨在探讨对应导联ST段改变与Ptfv_1的关系。124例中,男98例,女26例,平均年龄64.2岁。主要依据临床表现,心电图及血清酶学改变进行诊断。对应导联ST段下降系指胸前导联(V_1~V_6)至少有二个导联ST段下降≥0.1mV为异常。Ptfv_1测量方法:测V_1导联负相P波的深度(mm)和宽度(s),
In recent years, acute inferior myocardial infarction and chest lead corresponding ST segment decline more and more cause for attention. This article summarizes 124 cases of acute inferior myocardial infarction hospitalized in our hospital from 1968 to 1988, and aims to explore the relationship between ST lead changes and Ptfv_1 in corresponding leads. 124 cases, 98 males and 26 females, with an average age of 64.2 years old. Mainly based on clinical manifestations, ECG and serum enzyme changes in the diagnosis. Corresponding lead ST segment descent refers to the chest lead (V_1 ~ V_6) at least two lead ST segment decreased ≥ 0.1mV is abnormal. Ptfv_1 measurement method: measured V_1 lead negative P wave depth (mm) and width (s),
