RT Journal Article SR Electronic T1 Persistent lone atrial fibrillation — its progress after clinical diagnosis JF The Journal of the Royal College of General Practitioners JO J R Coll Gen Pract FD British Journal of General Practice SP 547 OP 549 VO 29 IS 206 A1 J. B. Close A1 D. W. Evans A1 S. M. Bailey YR 1979 UL http://bjgp.org/content/29/206/547.abstract AB Eighty-three patients whose atrial fibrillation appeared to be permanent and the sole cardiac abnormality at the time of diagnosis were followed for one to 19 years (mean 7.5 years). None suffered systemic embolism. Three died, none of cardiac disease. Sinus rhythm returned in seven. Another six developed features suggestive of other heart disease. In the remaining 67, the initial diagnosis of persistent lone atrial fibrillation remained tenable and they remained well. The medium-term prognosis for patients with this disorder seems good.
