Key result
Percutaneous circumferential pulmonary vein isolation induced an acute increase in mean heart rate from 54 to 62 bpm (P<0.001) and a significant reduction in short-term heart rate variability.

Acute HR rise after CPVI should not alter management; leaves open its value as a predictor of long-term outcome.

Does percutaneous circumferential pulmonary vein isolation induce acute changes in heart rate and heart rate variability in patients with symptomatic atrial fibrillation?
p-value: p=<0.001
Percutaneous CPVI induces acute acceleration of heart rate and attenuation of short-term heart rate variability, indicating vagal denervation, but these acute changes do not predict long-term clinical outcome.
KETELS et al. (2008) conducted an observational in symptomatic atrial fibrillation (n=46). percutaneous circumferential pulmonary vein isolation (CPVI) vs. baseline (pre-procedure) was evaluated on acute ablation-induced changes in heart rate and short-term heart rate variability (p=<0.001). Percutaneous circumferential pulmonary vein isolation induced an acute increase in mean heart rate from 54 to 62 bpm (P<0.001) and a significant reduction in short-term heart rate variability.
