WebMay 4, 2024 · The hallmarks of hyperacute T waves have been described for a century: First sign of occlusion: in 1918, the first experimental study on ECGs in acute coronary occlusion noted that, “immediately following the ligation the T-waves became more prominent…in some instances it exceeded the height of the R wave.” [2] WebT wave: The T wave represents the repolarization of the ventricles, which is the recovery of the electrical charge of the ventricles after depolarization. The T wave is usually rounded and slightly asymmetrical, with a duration of between 160 and 240 milliseconds. Other waves and intervals in an ECG signal include:
