WebApr 14, 2024 · The normal T wave is in the same direction as the preceding QRS complex. In leads V 1 and V 2, the T wave may be positive in spite of a dominantly negative QRS complex. Repolarization of the ventricular cells causes a flow of ions in a direction opposite to that of depolarization. It is, therefore, expected that direction of the T wave should ...
