Auricular Fibrillation in Normal Hearts

Abstract

AURICULAR fibrillation is not always associated with organic heart disease, and its presence may be the only sign attracting the examiner's attention to the heart. All cases of auricular fibrillation are fairly readily separated into two significant clinical groups — a minor group occurring in anatomically normal hearts and a major group occurring in damaged and diseased hearts. Emphasis should be placed on auricular fibrillation occurring in normal hearts because of its excellent prognosis, since this arrhythmia is most frequently observed in gravely damaged and decompensated hearts in which the prognosis is rather ominous.Auricular fibrillation occurring in normal hearts . . .
