Inclusion criteria

Inclusion criteria: We retrospectively analyzed consecutive paroxysmal atrial fibrillation (PAF) patients who were referred to Toyama Prefectural Central Hospital in Japan between January 2016 and June 2019 for their first ablation procedures.

Exclusion criteria

Exclusion criteria: We excluded patients with AF and antiarrhythmic drugs except for beta-blockers and with drugs known as the risk of prolonging QT (e.g., Erythromycin, Cilostazol, etc.). We also excluded patients undergoing artificial dialysis because of a change of electrolyte concentrations during dialysis intervals.
