A "square root" pattern of changes in the heart rate variability during the first year after circumferential pulmonary vein isolation for paroxysmal atrial fibrillation and their relation with long-term arrhythmia recurrence.

CONCLUSIONS: Sustained parasympathetic denervation during 12 months after CPVI was a marker of successful CPVI, whereas a 3-month post-CPVI SDNN reduction (ΔSDNN(post-CA[3 m])) of ≤ 25 ms predicted LRAF occurrence. PMID: 32049070 [PubMed - as supplied by publisher]
