Abstract
A patient in whom Wenckebach phenomenon was observed to coexist in the three distal branches of the specialized ventricular conduction system, with an intermittent trifascicular block producing a second degree A-V block, is described. Surface electrocardiogram demonstrated the presence of this phenomenon in the right bundle branch (RBB) and the anterior division of the left bundle branch (LBB). Evidence of the presence of Wenckebach phenomenon in the remaining fascicle was provided by His bundle recording.
