Denervation as a Common Mechanism Underlying Different Pulmonary Vein Isolation Strategies for Paroxysmal Atrial Fibrillation: Evidenced by Heart Rate Variability after Ablation
Figure 4
Serial changes of SDNN and rMSSD during five-year follow-up. (a) SDNN remained attenuated during 12-month follow-up in SPVI-S and CPVI-S subgroups, while recovered after 6 months in SPVI-R and CPVI-R subgroups. (b) rMSSD remained attenuated during 12-month follow-up in SPVI-S and CPVI-S subgroups, while recovered after 1 month in SPVI-R and CPVI-R subgroups. *.
