WebbT waves in leads V2 and V3 also invert in early childhood; in fact, upright T waves at a young age may be abnormal. They will progressively become upright in most children in the order of V3, V2, and V1 by the teenage years. This conversion is already becoming evident in the preteen patient, as V3 has a nearly flat to biphasic T wave. [3,7] Webb14.
