Electrocardiogram recording for 100 consecutive beats was performed 1 day after PVI. The patients were divided into two groups: those with reproducible APBs (\u22651 beat) during reassessment (APB group, <jats:italic>n<\/jats:italic>\u2009=\u200949) or those without (non\u2010APB group, <jats:italic>n<\/jats:italic>\u2009=\u2009157). Late recurrence was defined as atrial tachyarrhythmia recurrence 3\u201312 months after PVI. The impact of APB occurrence on outcomes was investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Late recurrence occurred in 19 patients (9.2%). The presence of low\u2010voltage areas, left atrial volume, and recurrence rate were higher in the APB group than in the non\u2010APB group. In the APB group, the patients with recurrence had lower prematurity index (PI, coupling interval of APB\/previous cycle length) compared to those without. Receiver\u2010operating characteristic analysis revealed PI (&lt;59.3) to be a predictive factor of recurrence (area under the curve: 0.733). The study subjects were then reclassified into three groups according to the absence of APB occurrence (<jats:italic>n<\/jats:italic>\u2009=\u2009157), presence thereof with PI\u2009\u2265\u200959.3 (<jats:italic>n<\/jats:italic>\u2009=\u200933), and presence with PI\u2009&lt;\u200959.3 (<jats:italic>n<\/jats:italic>\u2009=\u200916). The multivariate Cox models revealed that APB with PI\u2009&lt;\u200959.3 was an independent predictor for recurrence (hazard ratio, 8.735;
