A subset of patients with acute coronary artery occlusion requiring emergency revascularization, does not present with the typical ECG features of ST-segment elevation myocardial infarction (STEMI).Timely identification of these atypical presentations is crucial.
This report describes a 55-year-old male patient who was admitted to the emergency department with chest pain. The electrocardiogram (ECG) recorded atypical de Winter electrocardiographic changes and their evolution.
Coronary angiography confirmed the occlusion of the second diagonal branch (D2). The patient's condition improved after D2 balloon angioplasty.
De Winter electrocardiographic changes can also be observed in D2 occlusions and may present with milder manifestations. Timely recognition of these changes holds significant clinical value.
需要紧急血运重建的急性冠状动脉闭塞患者中，存在一部分不表现出典型 ST 段抬高型心肌梗死（STEMI）的心电图特征。及时识别这些非典型表现至关重要。
本报告描述了一位 55 岁男性患者，因胸痛就诊于急诊科。心电图（ECG）记录到非典型的 de Winter 心电图改变及其演变。
冠状动脉造影证实第二对角支（D2）闭塞。D2 球囊扩张后患者病情改善。
de Winter 心电图改变也可在 D2 闭塞中观察到，且可能表现为较轻的征象。及时识别这些改变具有重要的临床价值。
