May warrant AF screening in highly active men; hypothesis-generating and requires prospective validation before practice change.
High-intensity aerobic exercise increases the risk of atrial fibrillation in athletes, presenting unique management challenges where catheter ablation is increasingly preferred as first-line therapy.
Crinion et al. (2020) conducted a review in Atrial fibrillation. High-intensity aerobic exercise vs. Sedentary lifestyle or moderate exercise was evaluated. High-intensity aerobic exercise, especially in men, increases the risk of atrial fibrillation at a threshold of more than 1500 to 2000 lifetime hours.
