WebIn a right bundle branch block (RBBB), depolarization begins the way that it always does, in the sense that the impulse travels through the AV node and down the left bundle branch to the interventricular septum. 2 The septum is then activated by the LBB's posterior fascicle, and depolarization occurs in a left-to-right fashion. WebNov 6, 2012 · In right bundle branch block (RBBB) the conduction in the bundle to the right ventricle is slow. As the right ventricles depolarizes, the left ventricle is often halfway finished and few counteracting electrical activity is left. The last electrical activity is thus to the right, or towards lead V1. In RBBB the QRS complex in V1 is always ...
