WebWhat Does a Normal T Wave Look Like? Normal T waves are typically upright and generally follow the same direction as the QRS complexes. Hence T waves are upright (positive deflection) in leads 1, 2, aVL, aVF, and V2 through V6. The T waves are typically downward (negative deflection) in aVR. In leads 3, and V1, the T wave direction is variable.
