ST-segment elevation is the hallmark of acute transmural myocardial ischemia caused by acute occlusion of a coronary artery. ST-segment elevation is the major criterion for the patients with chest pain to immediate reperfusion therapy. Despite its clinical importance, the mechanism of ST-elevation remains unclear. Two patients are reported with proximal left anterior descending coronary occlusion but without ST-segment elevation. The distinct ECG patterns were tall, with symmetrical T-waves and upsloping and digoxin-like ST-segment depression. Patients with these ECG patterns need immediate coronary intervention.
ST段抬高是由冠状动脉急性闭塞引起的急性透壁性心肌缺血的标志。ST段抬高是胸痛患者立即进行再灌注治疗的主要标准。尽管其具有临床重要性，但ST段抬高的机制仍不清楚。报告了2例左前降支近端冠状动脉闭塞但无ST段抬高的患者。其独特的心电图模式表现为高大、对称的T波以及上斜型和洋地黄样ST段压低。具有这些心电图模式的患者需要立即进行冠状动脉介入治疗。
