It is rare to observe right ventricular infarction caused by isolated right ventricular branch occlusion. Isolated right ventricular infarction accounts for less than three percent of all cases of infarction. Generally, it is associated with occlusion of a non dominant right coronary artery or of a right ventricular branch. ECG can be misleading with ST segment elevation in anterior leads. We describe a patient admitted for chest pain with ST segment elevation in leads V1 to V3 associated with ST segment elevation in leads V3R and V4R. Coronary angiography demonstrated isolated total occlusion of the right ventricular branch. Thus, right precordial leads need to be done in every patient presenting with ST segment elevation in precordial leads V1 to V3 and not only in inferior myocardial infarction.
孤立性右心室分支闭塞导致右心室梗死的情况较为罕见。孤立性右心室梗死在所有梗死病例中占比不到3%。一般来说,它与非优势型右冠状动脉或右心室分支的闭塞有关。心电图可能会因前壁导联ST段抬高而产生误导。我们描述了一名因胸痛入院的患者,其V1至V3导联ST段抬高,同时伴有V3R和V4R导联ST段抬高。冠状动脉造影显示右心室分支孤立性完全闭塞。因此,对于每一位胸前导联V1至V3出现ST段抬高的患者,都需要进行右胸前导联检查,而不仅仅是在下壁心肌梗死时。
