Beat-to-beat variations in activation-recovery interval derived from the right ventricular electrogram can monitor arrhythmic risk under anesthetic and awake conditions in the canine chronic atrioventricular block model

Behavior of STV from the RV and LV is comparable. STVRVARI increases significantly before the occurrence of an arrhythmia in awake and anaesthetized conditions. This finding can be integrated into devices to monitor arrhythmic risk.
