Rbbb with left fascicular block
WebJul 3, 2009 · Introduction. Chronic bifascicular block (BFB) defined as left bundle branch block (LBBB) or right bundle branch block (RBBB) associated either with a left anterior fascicular block (LAFB) or left posterior fascicular block (LPFB) is a particular form of intraventricular conduction delay.

WebThe formal threshold for left anterior fascicular block (LAFB) is −45° not −30°, the latter being the cutoff for left axis deviation. LAFB, by itself, may widen the QRS slightly but usually not beyond 0.11–012 sec. Most cases of pure LAFB are associated with small r waves in the inferior leads and a small q wave in lead aVL.
