Does sinus rhythm deceleration zone mapping identify critical sites for localized reentrant atrial flutter?
Mapping deceleration zones during sinus rhythm may help identify candidate ablation targets as an adjunct to pulmonary vein isolation to prevent localized reentrant atrial flutter.
In patients with L-AFL, CI co-localized with DZ during baseline rhythm, suggesting that DZ mapping during SR may yield candidate targets for ablation as an adjunct to pulmonary vein isolation to prevent a subtype of AFL.
Woods et al. (Tue,) studied this question.
