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). WebA more subtle form of cardiomyopathy, arrhythmogenic right ventricular dysplasia, which typically presents with a left bundle branch PVC pattern, also needs to be considered, and clinical clues to this disorder are the presence of inverted T-waves in leads V1 through V3, the presence of low amplitude potentials, delayed slurred QRS in leads V1 and V2, and the …
