Key result
Diagnostic pacemaker monitoring showed premature atrial complexes were the most common AF onset scenario (48%), and sudden onsets were more frequent with repetitive AF (24% vs 0%, P=0.011).
Why the study?
What are the onset scenarios and potential arrhythmogenic triggers of atrial fibrillation in patients with recurrent, symptomatic, drug-refractory AF?

Pacemaker-detected AF onset variability may guide future trigger-specific approaches; leaves open whether such monitoring improves outcomes in refractory patients.

What are the onset scenarios and potential arrhythmogenic triggers of atrial fibrillation in patients with recurrent, symptomatic, drug-refractory AF?
Diagnostic pacemaker features reveal substantial intra- and interindividual variability in AF onset scenarios, with premature atrial complexes and bradycardia being the most common triggers.
Hoffmann et al. (2006) conducted an observational in recurrent, symptomatic, drug-refractory atrial fibrillation (n=98). Dual-chamber pacemaker monitoring was evaluated on Atrial fibrillation onset scenarios. Diagnostic pacemaker monitoring showed premature atrial complexes were the most common AF onset scenario (48%), and sudden onsets were more frequent with repetitive AF (24% vs 0%, P=0.011).
