First-degree atrioventricular block is significantly associated with incident atrial fibrillation in the population predominantly including participants aged ≥ 60 years.

ABSTRACT: Some previous studies demonstrated that first-degree atrioventricular block (f-AVB) was associated with incident atrial fibrillation (AF), while evidence is scarce regarding the association between f-AVB and incident AF in older populations. Therefore, we sought to investigate the association of f-AVB with incident AF in the population predominantly including participants aged ≥ 60 years. Eligible participants were residents in Kanazawa City, Japan aged ≥ 40 years who underwent 12-lead ECG at the National Japanese Health Check-up in 2013. Participants with AF detected at the baseline exam and those without adequate follow-up were excluded. f-AVB was defined as PR interval ≥ 220 ms based on the Minnesota code (6-3). The cumulative incidence of AF was estimated by the Kaplan-Meier curve anal
