Figure 1: Categories of bundle branch re-entry ventricular tachycardia. Type A employs the right bundle branch for antegrade conduction thus giving a left bundle branch block-like morphology also described as counterclockwise activation. Type B involves re-entry within the fascicles of the left bundle branch (LBB) (fascicular VT). Type C employs the LBB for antegrade activation, thus giving a right bundle branch block-like morphology also described as clockwise activation. #Diagnosis #BBRVT #Reentry #Ventricular #Tachycardia #Types #Categories
