It is rare to observe ST elevation in anterior derivations caused by right ventricular branch occlusion. We described the case of a patient with unstable angina who developed acute right ventricular myocardial infarction with ST-segment elevation in anterior precordial leads (V(1)-V(4)) shortly after coronary angiography. Coronary angiogram revealed total occlusion of the right coronary artery (RCA) proximally to the right ventricular branch. This reminds us that the presence of diffuse ST-segment elevation in the precordial leads could be due to acute RCA occlusion. The differentiation of these two entities is important, as their therapies are quite different.
由右心室分支闭塞导致前壁导联ST段抬高的情况较为罕见。我们描述了一例不稳定型心绞痛患者的病例,该患者在冠状动脉造影后不久出现急性右心室心肌梗死,并伴有胸前导联(V(1)-V(4))ST段抬高。冠状动脉造影显示右冠状动脉(RCA)在右心室分支近端完全闭塞。这提醒我们,胸前导联出现弥漫性ST段抬高可能是由于急性RCA闭塞所致。区分这两种情况很重要,因为它们的治疗方法有很大不同。
