ventricular conduction

Together, the bundle branches and Purkinje network comprise the ventricular conduction system.

Ventricular conduction is normal with wandering pacemaker, and thus the QRS complex is normal.

Ventricular escape (rate 20-40): originates in ventricular conduction system; no P wave, wide, abnormal QRS.

These data suggest an interaction between the antiarrhythmic agent and ischaemia - ie, the antiarrhythmic drug, which slows conduction as its usual mechanism of action, may have intensified the regional ventricular conduction delay accompanying ischaemia and caused ventricular fibrillation during ischaemic episodes.
