| Abstract: | In brief Prompted by President George Bush's episode of atrial fibrillation (AF) while jogging, the authors reviewed the cases of eight apparently normal, physically active men who had AF. Episode triggers included exercise and the ingestion of caffeine, alcohol, cold water, and ice cream. None of the patients had clinical hyperthyroidism. One patient had a subsequent stroke, despite anticoagulation therapy. Most of the patients were able to prevent recurrence by avoiding triggering factors. When AF recurs despite such avoidance and the use of digoxin or beta-blockers, a class 1A antiarrhythmic agent can be tried. |
