Key result
Paroxysmal AF features a ~51% higher prevalence of repetitive conduction patterns than persistent AF.
Why the study?
As a first step towards repetitive pattern mapping to guide AF ablation, the authors evaluated repetitive conduction patterns that may indicate preferential conduction paths or stationary AF sources.
Population
Persistent AF (n = 9) and paroxysmal AF (n = 11) patients

Repetitive patterns may warrant investigation as ablation targets in paroxysmal AF; leaves open their role in progression and clinical outcomes.

High-density epicardial mapping reveals that repetitive conduction patterns are more frequent, larger, and more stable in paroxysmal AF compared to persistent AF, which may inform future ablation strategies.
Rosmalen et al. (2020) conducted an observational in Atrial fibrillation (n=20). High-density epicardial contact mapping vs. Persistent AF vs Paroxysmal AF was evaluated on Prevalence of repetitive conduction patterns (p=< 0.01). Repetitive conduction patterns were more prevalent in paroxysmal AF compared with persistent AF (median 59% vs 39%, P<0.01).
