Fig. 3From: Post Procedural Peak Left Atrial Contraction Strain Predicts Recurrence of Arrhythmia after Catheter Ablation of Atrial FibrillationKaplan–Meier analyses of arrhythmia recurrence according to PACS1-day cut-off value (-12%) in all patients. The analyses showed significant difference in the cumulative probability of arrhythmia recurrence between patients with PACS1-day > -12% and PACS1-day ≤ -12%.
