Typical features include: Inversion of lead I Reversal of Leads aVR and aVL Reversal of Leads II and III WebSep 22, 2024 · The T wave is the ECG manifestation of ventricular repolarization of the cardiac electrical cycle. The T wave is normally upright in leads I, II, and V3 to V6; inverted in lead aVR; and variable in leads III, aVL, aVF, V1, and V2. Thus, T-wave inversions in leads V1 and V2 may be fully normal. A variety of clinical syndromes can cause T-wave.
