Isolated right ventricular infarction (RVI) is a rare event. The electrocardiographic (ECG) pattern of RVI, ST-elevation in lead V4R and in anterior chest leads V1-3 is similar to that of a proximal occlusion of a small, nondominant right coronary artery (RCA). The ECG changes may be misinterpreted as signs of infarction of the anterior wall. This paper describes a case of isolated temporary occlusion of the major side branches of the RCA during percutaneous coronary intervention, recognized by angiography findings and typical ECG changes. This case demonstrates how one might avoid wrong decisions even in the catheterization laboratory by putting attention to the anatomical interpretation of the ECG.
孤立性右心室梗死（RVI）是一种罕见的情况。RVI的心电图（ECG）表现，即V4R导联及胸前导联V1 - 3的ST段抬高，与小的、非优势型右冠状动脉（RCA）近端闭塞时的表现相似。这些ECG改变可能被误诊为前壁梗死的征象。本文描述了1例经皮冠状动脉介入治疗期间RCA主要分支发生孤立性临时闭塞的病例，该病例通过血管造影结果及典型的ECG改变得以确诊。此病例表明，即使在导管室，通过关注ECG的解剖学解释，也可避免做出错误的诊断。
