Why the study?
Atrial tachycardia episodes during AF ablation are generally considered a consequence of ablation, but their spatial relationship with dispersion and ablation regions remains unclear.
Localized atrial tachycardias during persistent AF ablation originate primarily within dispersion regions rather than near ablation lesions, suggesting they are stabilized AF drivers rather than ablation-induced arrhythmias.
No takes yet. Share an insight, caveat, or question.
ATs arise from dispersion regions remote from ablation lesions; hypothesis-generating for dispersion-guided strategies in persistent AF.
Gitenay et al. (2021) studied this question.
