WebJul 13, 2024 · Sequence of conduction in RBBB: 1) Left ventricular activation via the left bundle (black arrow) occurs normally. 2) Septal depolarisation (yellow arrows) is thus unaffected, producing a normal early QRS complex. 3) Activation of the RV originates across the septum. The resultant depolarisation vector (red arrow) produces delayed R waves in ...

WebFigure 2. Right bundle branch block (RBBB) and left bundle branch block (LBBB). Note that the paper speed is 50 mm/s (1 large box equals 100 ms). The hallmark of both RBBB and LBBB is the QRS duration which is by definitions 120 ms or longer. The distinction between RBBB and LBBB is simple, as illustrated in this figure.
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.
