摘　　要：本文对１３８例急性下壁心肌梗塞的心电图改变进行了系统分析，以探讨常规导联对合并右室梗塞的诊断价值。结果在明Ⅲ／Ⅱ导联ＳＴ段抬高比值大于１．０，胸前导联ＳＴ段递减性抬高，Ｖ２导联ＳＴ段压低小于ａＶＦ导联ＳＴ段抬高的一半和室间隔Ｑ波消失与Ｖ３Ｒ～Ｖ５Ｒ抬高相比对合并右室梗塞的准确率分别为６０％，９０％，８０．８％和８２．３％。并提出胸前导联ＳＴ段抬高顺序有助于鉴别急性下壁心肌梗塞是否合并右室梗塞或前壁梗塞。联合应用这些心电图指标可提高右室梗塞的诊断准确率。For the early diagnosis of acute right ventricular infarction,the ECG changes of acute inferior myocardial infarction were analysed in 138 cases.The results showed the diagnosis accuracy of the four ECG markers in routine leads.Ⅲ/ⅡST elevation>1.0,decrease ST elevations in precordial leads(V1/V5),V2 ST decreation/aVF ST elevation<0. 5 and septal Q wave disapperence,were 60.0,90.0,80.8 and82.3%respectively.In addition,the ST elevation order in precordial leads have important values in the differential diagnosis of right ventricular infarction and anterior wall infarction.In general,the ECG markers of routine leads have early diagnosis value for the right ventricular myocardial infarction and the proximal stenosis of right coronary artery.
