Fixed t wave inversion

WebA wave starts travelling. It moves, hits the wall, then flattens, then is created again underneath (inversed), and then starts travelling back. Question: The inversion itself … Web11. T Wave Abnormalities Introduction. The T wave is the most labile wave in the ECG. T wave changes including low-amplitude T waves and abnormally inverted T waves may be the result of many cardiac and non-cardiac conditions. The normal T wave is usually in the same direction as the QRS except in the right precordial leads (see V2 below).
