WebFeb 18, 2014 · What is the rationale behind biventricular pacing in ventricular pacing-dependent patients with normal LV function? Right ventricular pacing induces interventricular and LV-intraventricular dyssynchrony similar to intrinsic left bundle branch block (LBBB). This can lead to an increase in LV volumes, and a decrease in … WebThe bundle of His splits into two branches in the interventricular septum: the left bundle branch and the right bundle branch. The left bundle branch activates the left ventricle, while the right bundle branch activates the right ventricle. The left bundle branch is short, splitting into the left anterior fascicle and the left posterior fascicle.
