Denervation as a Common Mechanism Underlying Different Pulmonary Vein Isolation Strategies for Paroxysmal Atrial Fibrillation: Evidenced by Heart Rate Variability after Ablation
Figure 2
Comparison of HRV before and after CPVI. (a) Time-domain parameters of HRV significantly decreased after CPVI, both in the success and recurrence subgroups. (b) Frequency-domain characteristics of HRV significantly decreased after CPVI, both in the success and recurrence subgroups. Abbreviations are as in Figure 1. *.
