Atrial Fibrillation in Endurance Training Athletes: Scoping Review

Background: Moderate regular physical activity is indicated to avoid atrial fibrillation (AF), whereas athletes should be counseled that long-lasting vigorous sports engagement may cause AF, according the 2016 European Society of Cardiology (ESC) recommendations for AF treatment. Exercise and are complex. Objectives: To evaluate relationship between Endurance training in addition starting point/trigger by which Training causes impairment cardiac function considering time intensity training. Materials Methods: We synthesized evidence from articles published PubMed, EMBASE, SciELO databases using their respective Boolean operators. A total 112 original related endurance up year 2023 were reviewed. Results: Our study verified multiples aspects genesis athletes, such as adaptations exercise, disturbances injury biomarkers, sex differences role risk, body composition (height, weight, fitness) pathogenesis. Conclusions: Variations structure (increased thickness size myocardial fibrosis) significant increases vagal tone (sinus bradycardia imbalances sympathetic parasympathetic activation) shorten refractory period shortening induce onset re-entrance mechanisms, serve ectopic triggers can lead AF.
