"elevation of the ST segment in lead aVRusually > 0.5 mm"
"While originally described as an early, static, and unique finding, the de Winter T wave pattern has subsequently been demonstrated to precede classic ST segment elevation, as well as occur in other coronary lesions, including left main coronary artery occlusion. The described pattern appears as follows 1:"
"upsloping ST segment depression at the J pointsome or all of precordial leads V1-6"
"elevation of the ST segment in lead aVRusually > 0.5 mm"
"normal to slightly prolonged QRS duration"
"prolonged QRS duration"
"left main coronary artery occlusion 3depression of ST segments typically diffuse"
"may produce the biphasic T waves of Wellen's syndrome"
Expected headings
"ECG"
"An electrocardiographic finding suggestive of impending myocardial infarction, the de Winter's pattern (or "de Winter's T-waves") describes an abnormality thought to be indicative of acute occlusion of the proximal left anterior descending coronary artery (LAD) 2. Timely recognition of this pattern is crucial; earlier percutaneous coronary intervention (PCI) reduces morbidity and mortality in myocardial infarction."
