An abnormal heart rhythm giving specific electrocardiogram changes and attacks of paroxysmal tachycardia. It is a congenital condition caused by an accessory bundle between the atria and ventricles. There is no evidence that athletic exertion makes sudden death from WPW syndrome more likely. However, those with very low resting pulse rates, such as distance runners, may be more vulnerable to ectopic beats.
