De Winter ECG Pattern Can Be A Temporary ECG Phenomenon Related To Severe Stenosis of The Left Circumflex Coronary Artery: A Case Report

The de Winter ECG pattern consisting of ST-segment depression and tall symmetrical T waves on ECG, known as an ST elevation equivalent, accounts for approximately 2% of patients with occlusion of the proximal left anterior descending coronary artery (LAD). These patterns are considered static and persistent and are, on average, recorded 1.5 hours after onset. Here, we describe a case of the de Winter ECG pattern as a temporary ECG phenomenon associated with left circumflex coronary artery (LCX) stenosis.
