Improvement of minimizing ventricular pacing in dual chamber pacemaker / 中国实用内科杂志

The data from clinical studies have shown that conventional dual chamber pacing results in high percentages of right ventricular apical pacing,which causes electromechanical desynchronization and has been linked to an increased risk of heart failure and atrial fibrillation.Nowadays,we can use some special algorithms to minimize ventricular pacing,promote atrioventricular conduction and improve hemodynamics in patients with pacemakers.This review summarizes the genesis,some algorithms and clinical studies about minimizing ventricular pacing.
