The sinus node disease is approximately 50 % of pacemaker implants. Atrial fibrillation is a frequent comorbidity of pacemakers and is associated with heart failure, stroke and death.
While unnecessary stimulation of the right ventricle has a long term detrimental effect, including an increased risk of atrial fibrillation. In the ventricular pacing mode (MVP, managed ventricular pacing) stimulation occurs in both chambers, reducing unnecessary right ventricular pacing only.
The study included patients with class I or II indication for dual-chamber pacemakers and prior atrial tachycardia but no history of permanent atrial fibrillation or AV block grade 3. At follow-up there was no difference in mortality or rehospitalization but a lower incidence of permanent atrial fibrillation (61% reduction in the group DDDRP versus DDDR ) .
Conclusion:
In patients with symptomatic bradycardia pacing modality DDDRP + MVP pacemaker, proved superior to the dual chamber pacing.
