Abstract

A retrospective study was undertaken to determine the incidence of spontaneous atrial fibrillation (AF) in a group of asymptomatic pilots. The electrocardiograms of 13,037 aircrew members accumulated between 1964 and 1986 were reviewed and those coded for AF were extracted. In each case an attempt was made to investigate factors relating to the onset, course, and prognosis of the AF. Eight subjects (mean age 50.1 years) were found to have AF. Of this group, two had a single isolated episode of AF for which a specific precipitating factor was implicated, three had recurrent paroxysmal AF of which one progressed to chronic persistent AF, and three had chronic persistent AF from the outset. The mean follow-up period for the eight subjects was 13.6 years. The two pilots who had isolated attacks of AF have thus far had no subsequent episodes of AF. Five of the remaining six have been completely well, while one required treatment for an embolus to his left leg. Concerning the aeromedical implications, we believe that pilots demonstrating single isolated episodes of AF in the presence of a normal heart, and in whom recovery is complete, should be allowed to return to full aviation duties on a waiver clause. Patients with chronic AF, lone AF, or paroxysmal AF should be excluded from all flying duties.
