WebTall R Wave in V1: The Four Categories. Let’s take a logical approach to the meaning of a tall R wave in V1. First, understand that V1 is the only right-sided lead in the standard 12-lead ECG, and therefore, a tall R wave in V1 represents increased net rightward depolarization. Second, remember that the causes of increased right-sided ... Incomplete right bundle branch block (IRBBB) is an conduction abnormality in the right bundle branch block. While a complete RBBB has a QRS duration of 120 ms or more, an incomplete block has a wave duration between 110 and 120 ms.
