If the sinus node and the atrioventricular (AV)junction fail,the ventricles depolarize at their own intrinsic rate of 20 to 40 times per minute.This is called an idioventricular rhythm and is naturally protective mechanism.Rather than trying to abolish the ventricular beats,the aim of treatment is to increase the effective heart rate (HR)and reestablish dominance of a higher pacing site such as the sinus node or the AV junction.Usually,a temporary pacemaker is used to increase the HR until the underlying problems that caused failure of the other pacing sites can be resolved.
