WebDec 3, 2016 · T wave inversion in V1 and V2 can be secondary repolarization abnormality due to change in depolarization sequence due to right bundle branch block (secondary T wave abnormality). Arrow head T inversion in aVL seems to be a primary repolarization abnormality (primary T wave abnormality), indicating myocardial disease like ischemia or … WebNov 16, 2024 · However, right bundle branch block (RBBB) delays activation of the right ventricle to the late phase of depolarization. As a result, the terminal QRS vector is oriented anteriorly and to the right. This vector points toward the positive axis of the anterior-posterior lead V1 and away from the positive axis of left-right lead V6.
