Lone atrial fibrillation in vigorously exercising middle aged men: case-control study

Abstract: Regular physical exercise reduces cardiovascular morbidity.1 2 However, our clinical impression is that atrial fibrillation is quite common in otherwise healthy middle aged men engaged in long term vigorous endurance sports. We therefore compared the prevalence of atrial fibrillation in middle aged men doing intense endurance training and men from the general population. We chose top level veteran orienteers to represent subjects doing long term vigorous exercise. A high position in the veteran ranking list is an indicator of years of intense training.
