"Web17 de fev. de 2016 · However, the earliest findings on an ECG are subtle changes in the T-wave shape and size. When a coronary artery is occluded, within the first 30 minutes, the T-wave amplitude increases [2]. The next changes are ST-segment elevation and loss of the R-wave amplitude. If the vessel remains occluded, Q-waves develop. " - Normal t wave amplitude ekg
