Overview
Bifascicular block is a conduction abnormality in the heart where two of the three main fascicles of the His/Purkinje system are blocked.
Most commonly, it refers to a combination of right bundle branch block (RBBB) and either left anterior fascicular block (LAFB) or left posterior fascicular block (LPFB).
Some authors consider left bundle branch block (LBBB) to be a technical bifascicular block, since the block occurs above the bifurcation of the left anterior and left posterior fascicles of the left bundle branch.

Class I1. Permanent pacemaker implantation is indicated for advanced second-degree AV block or intermittent third-degree AV block. (Level of Evidence: B) 2. Permanent pacemaker implantation is indicated for type II second-degree AV block. (Level of Evidence: B) 3. Permanent pacemaker implantation is indicated for alternating bundle-branch block. (Level of Evidence: C) Class IIaClass IIbClass III |
