Description:

Pulmonary vein isolation (PVI) is the cornerstone in the treatment of patients with paroxysmal atrial fibrillation (PAF). Some research has suggested studies have shown that modification of ganglionated plexuses (GP), performed with PVI, could lead to even better outcomes. The aim of this study was to determine the effect of PVI on the autonomic system. Heart rate variability (HRV) was used as a marker of autonomic system activity. Twenty-six PAF patients underwent PVI (PVI group) and twenty patients underwent PVI plus a GP ablation (GP group). In each group, 5 min long ECG signals obtained before and after the electrophysiology EP study were analyzed. Time and frequency domain parameters were evaluated. Vagal responses during ablation were observed in 15 (58 %) patients in the PVI group and in 12 (60 %) patients in the GP group. The change in normalized power in the low frequency (LF) and in the LF/HF ratio, before and after ablation, was statistically significant in both groups (LF/HF 2.6±1.6 before vs. 1.4±1.7 after ablation in PVI group and LF/HF 3.3±2.6 before vs. 1.8±1.9 after ablation in the GP group). Relative to heart rate variability parameters, there were no differences between PVI and PVI + plus GP ablation.
