Idiopathic atrial fibrillation as a risk factor for mortality.The Paris Prospective Study I

Abstract

Idiopathic atrial fibrillation describes atrial fibrillation of unknown origin occurring without heart disease. Mortality is considered unaffected by idiopathic atrial fibrillation. We used the long follow-up period (23 years on average) of the Paris Prospective Study I to assess the mortality of idiopathic atrial fibrillation subjects in middle-aged men.
