The 12-lead electrocardiogram is an easily obtained, non-invasive method to assist in the diagnosis of an acute myocardial infarction. Traditional electrocardiographic criteria for diagnosing inferior myocardial infarction emphasize abnormalities of the initial large Q wave or ST segment elevation in leads II, III, and aVF. We report a case that has acute R-wave loss in inferior leads as an initial manifestation of acute inferior wall myocardial infarction. The patient was stabilized by coronary angioplasty.
12导联心电图是一种易于获取的无创方法，有助于诊断急性心肌梗死。传统的诊断下壁心肌梗死的心电图标准强调Ⅱ、Ⅲ和aVF导联初始大Q波或ST段抬高的异常。我们报告一例以下壁导联急性R波丢失为急性下壁心肌梗死初始表现的病例。该患者通过冠状动脉成形术病情稳定。
