Figure 9‐7 — Twelve‐lead ECGs and schematic illustrations of reentrant circuits for BBR and interfascicular reentry tachycardias. A, Type A: Typical type of BBR in which retrograde conduction occurs via the left bundle branch (LBB) and anterograde conduction over the right bundle (RBB) branch. B, Type B: Interfascicular reentry with anterograde and retrograde conduction over opposing fascicles of the LBB. C, Type C. Reversal of the circuit depicted in type A AVN, Atrioventricular node; BBR, bundle branch reentry; HB, His bundle; LAF, left anterior fascicle; LPF, left posterior fascicle; RBB, right bundle branch (Modified from Nogami A: Purkinje‐related arrhythmias. Part I: Monomorphic ventricular tachycardias. Pacing Clin Electrophysiol 34:624‐650, 2011.40)
