Immediately after coronary artery occlusion, the ECG undergoes predictable temporal changes. Classically, coronary vessel occlusion leads to elevation of the ST-segments (producing STEMI). However, the earliest findings on an ECG are subtle changes in the T-wave shape and size. When a coronary artery is occluded, …
