Isolated right ventricular myocardial infarction (RVMI) rarely occurs and accounts for only 3% of all myocardial infarction cases. In the literature, there are several reported isolated RVMI cases with precordial ST-segment elevation. We describe a 45-year-old man with marked ST-segment elevations in leads V1 through V4 accompanied by slight ST-segment elevations in the inferior leads (III, aVF) caused by acute occlusion of a nondominant small right coronary artery proximal to the conus branch causing isolated RVMI.
孤立性右心室心肌梗死（RVMI）很少发生，仅占所有心肌梗死病例的3%。在文献中，有几例报告的伴有胸前导联ST段抬高的孤立性RVMI病例。我们描述了一名45岁男性，其V1至V4导联出现明显的ST段抬高，同时下壁导联（III、aVF）出现轻微ST段抬高，这是由于圆锥支近端一支非优势型小右冠状动脉急性闭塞导致孤立性RVMI。
