Abstract: The de Winter electrocardiogram（ECG） pattern is considered as the ECG manifestation for acute ST-segment elevation myocardial infarction （STEMI），based on the evidence of clinical coronary angiography suggested severe proximal stenosis or complete occlusion of the anterior descending branch，and its intrinsic relationship with the typical four-stage ECG findings of STEMI is not clear.In this paper，we analyzed the changes on the ECGs with de Winter pattern of a case of acute STEMI during the whole period of treatment，and reviewed relevant studies，then assessed the relationship between acute STEMI and de Winter ECG，in order to provide new ideas for the further understanding of de Winter ECG.

摘要： de Winter心电图表现被视为急性ST段抬高型心肌梗死（STEMI）的心电图，证据源于患者临床冠状动脉造影提示左前降支（LAD）近端严重狭窄或完全闭塞，这与既往STEMI典型四期心电图表现内在关系如何不明确。本文收集了1例急性STEMI患者全程心电图演变及国内外相关文献，试分析急性STEMI与de Winter心电图的内在联系，旨在为进一步认识de Winter心电图提供新思路。
