The atrial effective refractory period (AERP) and atrial conduction time (ACT) were measured via electrophysiology before and immediately after ablation, and P\u2010wave indices were measured via electrocardiography before and within 24\u2009h after ablation. Follow\u2010up visits were conducted for at least 1\u2009year or until relapse.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Different approaches of ablation caused a fairly significant increase in the shortest P\u2010wave duration and AERP in both the proximal coronary sinus (PCS) and distal coronary sinus (DCS) but caused a shortened P\u2010wave dispersion. No different effect was found at the AERP among the three modes. Compared to patients who received CA, among patients who received RFA, a significant reduction in total ACT and right ACT was seen. Statistically, there was a weakly positive association between changes in total ACT and early recurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Injury during ablation for PAF was associated with an increase in the AERP but not in the ACT. Total ACT and right ACT were shorter after RFA than after CA. The increase in total ACT were slightly predictive of early recurrence.<\/jats:p><\/jats:sec>","DOI":"10.1002\/clc.23617","type":"journal-article","created":{"date-parts":[[2021,6,2]],"date-time":"2021-06-02T01:00:06Z","timestamp":1622595606000},"page":"938-945","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The
