The de Winter electrocardiograph (ECG) pattern in patients with chest pain is associated with occlusion of the proximal left anterior descending (LAD) artery. These patterns were once considered stable conditions, without dynamic evolution of ECG. Recently, several case reports have indicated that this ECG pattern may evolve into ST-elevation myocardial infarction (STEMI) or may follow the ECG manifestations of STEMI. However, our case report reveals a dynamic evolution from the de Winter pattern to STEMI and then to a normal ECG pattern.

de Winter心电图模式的动态演变

胸痛患者的 de Winter 心电图 (ECG) 模式与左前降支 (LAD) 近端动脉闭塞有关。这些模式曾经被认为是稳定的条件，没有心电图的动态演变。最近，一些病例报告表明这种心电图模式可能演变为 ST 段抬高心肌梗死 (STEMI) 或可能遵循 STEMI 的心电图表现。然而，我们的病例报告揭示了从 de Winter 模式到 STEMI 再到正常 ECG 模式的动态演变。
