Anterior and inferior ST elevation on electrocardiography (ECG) in patients with acute myocardial infarction is uncommon. ST-segment elevation due to right ventricular infarction induced by right coronary occlusion may extend from V1 to V3/V4, resembling the pattern of transmural ischemia of the anterior wall of the left ventricle. In addition, a wraparound left anterior descending (LAD) artery can produce ischemia manifesting as ST-segment elevation in the anterior and inferior leads. Our case report reveals dynamic ST-segment changes in acute inferior myocardial infarction, including the appearance of the shark fin ECG pattern, unlike what has been reported before.
心电图（ECG）显示急性心肌梗死患者前下壁 ST 段抬高并不常见。右冠状动脉闭塞导致的右心室梗死引起的 ST 段抬高可从 V1 延伸至 V3/V4，类似于左心室前壁透壁性缺血的模式。此外，环绕性左前降支（LAD）动脉可导致缺血，表现为前下导联 ST 段抬高。我们的病例报告揭示了急性下壁心肌梗死中动态的 ST 段变化，包括出现鲨鱼鳍心电图模式，这与之前报道的不同。
