T‐wave inversion (TWI) is defined as negative T‐wave of ≥1 mm in depth in two or more contiguous leads, with exclusion of leads aVR, III, and V1.[1]The presence of TWI at 12‐lead electrocardiogram (ECG)...
T-wave inversion T-wave corresponds to the phase of rapid repolarization of the ventricular action potential. In the 12-lead ECG of adults, the normal T-wave is inverted in aVR; upright or inverted in leads aVL, III, and V1; and upright in limb leads I, and II, and in V3 to V6...
