WebDe Winter’s T waves. De Winter’s T Waves were first described by De Winter in an article to the editor of the New England Journal of Medicine in 2008 (1). They are considered an ST-elevation myocardial infarction (STEMI) equivalent and knowledge of this sign is important as ST depression is not the classic appearance of an STEMI. WebT peak -T end (T p-e) is the distance between T-wave peak point and the returning point to the isoelectric line. The T p-e interval reflects the transmural dispersion of repolarization [50]. Some studies revealed a relationship between T p-e and ventricular arrhythmias, heart failure, and sudden cardiac death [51,52].
