 abstract={Heart rate variability (HRV), blood pressure variability (BPV) and spontaneous baroreflex sensitivity (BRS) are useful tools for the assessment of autonomic cardiovascular control. Aim of the study was to evaluate their role in prediction of late atrial fibrillation (AF) recurrence. Methods: In 60 patients with history of AF beat-to-beat BP monitoring and 24-hour ECG monitoring were performed. Baroreflex function was calculated as alpha coefficient, modulus of transfer function, sequence technique and baroreflex effectiveness index- BEI. Results: In the 6-month fellow-up 48,3% patients had late AF recurrence. In the AF recurrence group as compared with patients with persisting sinus rhythm an increased parasympathetic modulation in HRV, higher spontaneous BRS, and no differences for BPV and BEI was observed. In the multivariate analysis spontaneous BRS, HRV indices and AF duration were significant predictors of late AF recurrence. Conclusions: Patients with late AF recurrence are characterized by increased parasympathetic cardiac modulation. lndices of spontaneous BRS and HRV are independent predictors of late AF recurrence. BPV does not have a role in predicting late AF recurrence. The noninvasive method of spontaneous BRS and HRV assessment has a clinical value for early identification of patients at higher AF recurrence rate and thus enabling the prevention of further episod},
