急性下壁心肌梗死(AIMI)常伴有右室受累。本文旨在评价根据右心前导联V_(4R)的ST段抬高诊断右室梗死(RVI)是否影响AIMI病人的预后。对象和方法根据典型胸痛持续>30分钟,Ⅱ、Ⅲ、αVF导联中有2个或以上的ST段抬高≥0.1mV和血清CK水平在入院24小时内增加至正常值2倍以上的200例连续AIMI患者,平均年龄61.5±6岁,胸痛至入院时间平均6.1±4.6小时。入院后作标准12导联心电图和右心前导联心电图(V_(3R)至V_(6R))。记录各导联出现的ST段抬高(≥0.1mV)和异常Q波。把V_(4R)出现的ST段抬高作为
Acute inferior myocardial infarction (AIMI) is often associated with right ventricular involvement. This article aims to evaluate whether the diagnosis of right ventricular infarction (RVI) affects the prognosis of patients with AIMI based on ST elevation of the V_ (4R) right anterior cardiac lead. Subjects and Methods According to typical chest pain lasting more than 30 minutes, two or more ST segment elevation in grade II, III, and αVF leads to ≥0.1 mV and serum CK levels increase to more than two times normal within 24 hours of admission Cases of continuous AIMI patients, the average age of 61.5 ± 6 years, chest pain to hospital time average of 6.1 ± 4.6 hours. After admission, the standard 12-lead ECG and right ventricular lead ECG (V_ (3R) to V_ (6R)) were used. ST segment elevation (≥0.1 mV) and abnormal Q waves recorded in each lead were recorded. The ST elevation at V_ (4R) is taken as
