AF onset cycle length dynamics may differ by AF subtype; leaves open whether they predict progression or guide therapy.
What are the electrophysiological differences at the spontaneous onset of paroxysmal versus persistent atrial fibrillation?
Persistent and sustained AF episodes demonstrate a more rapid degeneration into fibrillatory activity compared to nonsustained AF episodes.
Weber et al. (2007) studied this question.
