急性下壁心肌梗死常合并正后壁及右心室心肌梗死,诸多资料显示心电图检查常致漏诊。在临床工作中,经常发现常规12导联心电图胸前导联V1～V3,特别是V2导联ST段改变,对指导作图、减少漏诊率,尤其是对合并右心室梗死的早期诊断具有重要意义。本文对费县人民医院8年来收治的78例资 Acute inferior wall myocardial infarction is often associated with posterior wall and right ventricular myocardial infarction, many data show that ECG often missed diagnosis. In clinical practice, it is often found that the changes of ST segment in the lead of the conventional 12-lead electrocardiogram, that is, the V1 ~ V3, especially the V2 lead, are important in guiding the mapping and reducing the rate of misdiagnosis, especially for the early diagnosis of combined right ventricular infarction significance. In this paper, Fei County People’s Hospital for eight years admitted 78 cases of capital
