TL;DR: Right ventricular pacing is conventionally accompanied by a QRS complex with a left bundle branch block (LBBB) morphology, but occasionally, right ventricular stimulation has been reported to result in a right bundle branch blocks (RBBB), a widely differing QRScomplex morphologies associated with differentright ventricular endocardial stimulation sites are described.
