Pathophysiology
         
Ventricular escape beat C15, C25, C26, C27  

When the rate of supraventricular impulses arriving at the AV node or ventricle is less than the intrinsic rate of the ectopic pacemaker, a ventricular escape beat may occur.  The QRS complexes of a ventricular escape beat are broad (≥ 120 ms) and can have a LBBB or RBBB morphology at a rate of 20-40 bpm.
