Key result
Long-term VVI pacing was associated with the occurrence of left and right atrial disease, left atrial hypertrophy, and progression to atrial fibrillation.
Why the study?
Does VVI pacing compared to DDD pacing affect the evolution of P wave characteristics and progression to atrial fibrillation in patients with pacemakers?
Population
285 patients after pacemaker implantation
Comparison
VVI pacing vs DDD pacing
Design
Cohort
Follow-up

Warrants caution with long-term VVI pacing due to atrial risks; leaves open need for randomized confirmation of DDD superiority.
Observational (n=285)
Does VVI pacing compared to DDD pacing affect the evolution of P wave characteristics and progression to atrial fibrillation in patients with pacemakers?
Long-term VVI pacing is associated with adverse atrial remodeling, including atrial disease, hypertrophy, and progression to atrial fibrillation.
Snoeck et al. (1990) conducted an observational in Pacemaker implantation (n=285). VVI pacing vs. DDD pacing was evaluated on Evolution of P wave characteristics, occurrence of atrial disease, and progression to atrial fibrillation. Long-term VVI pacing was associated with the occurrence of left and right atrial disease, left atrial hypertrophy, and progression to atrial fibrillation.
