AF stabilization over 1 month. (A) Percentage (%) of horses in stable, self-sustained AF (≥ 24 h) after induction by high-rate atrial pacing (10 Hz). Induction of stable AF required 6 ± 4 days of pacing. (B) Longitudinal assessment of AF stability and progression by AF cycle length (AFCL) from right atrial intra-atrial electrogram recordings 3, 5, 11, 17, 29, and ∼40 days after AF induction. The red dotted line indicates the time point of the terminal high-density atrial mapping experiments. Statistical significance is defined as p < 0.05 and is marked with an asterisk ().
