WebThe amplitude of the T wave should not exceed 5 mm in limb leads and more than 10 mm in precordial leads, with the amplitude highest in V2-V3 leads. Amplitude diminishes with increasing age. Negative T waves, also known as T wave inversions, from V1 to V4 leads are frequently found in children and are normal. T wave inversion is less commonly ... WebIn the intermediate leads, V2 and V3 the T wave is often inverted in early childhood and there is a progression to the T wave becoming upright in the sequence V3, V2, V1. To illustrate the point, 50% of normal 3–5 year old children will have inverted T waves in V2 but in the 8–12 year age group inverted T waves in V2 will be present in only 5–10% of individuals.
