Key result
An additional activation delay during organized atrial fibrillation was 100% sensitive and 99% specific for impending organization into typical atrial flutter.
Why the study?
What is the sequence of electrophysiological events during the conversion of atrial fibrillation to typical atrial flutter in humans?
Observational (n=10)
What is the sequence of electrophysiological events during the conversion of atrial fibrillation to typical atrial flutter in humans?
The conversion of atrial fibrillation to typical atrial flutter follows a remarkably stereotypical pattern of endocardial activation, characterized by increasing cycle length and specific activation delays.

May flag impending flutter during organized AF ablation; hypothesis-generating from Level 5 data and requires prospective confirmation.
Roithinger et al. (1997) conducted an observational in Atrial fibrillation and atrial flutter (n=10). Electrophysiological mapping was evaluated on Sequence of events preceding conversion to atrial flutter. An additional activation delay during organized atrial fibrillation was 100% sensitive and 99% specific for impending organization into typical atrial flutter.
