Maintains coordinated atrioventricular relationship by synchronizing ventricular beats to atrial activity.
Prevents syncope during atrioventricular block.
With sinus node disease slightly reduces the risk of atrial fibrillation associated compared with ventricular pacing.
Does not reduce mortality and has minimal effect on stroke and heart failure risk in sinus nodal disease.
In patients with implantable cardioverter-defibrillator can lead the increased risk of heart failure and death in patients with sinus node disease.
