Abstract A retrospective study of the incidence of atrial fibrillation in 703 consecutive patients who had undergone selective coronary arteriography and left ventricular catheterization between November 1986 and May 1992 was undertaken. The study group included 136 patients with significant coronary stenosis (> 50\% diameter reduction) without previous myocardial infarction (group I), 157 with a history of myocardial infarction (group II), 326 with chest pain and normal coronary angiography (group III), 72 with valvular disease (group IV), and 12 with cardiomyopathy (group V). Clinical and electrocardiographic evidence of atrial fibrillation was documented in 75 patients (10.7\%), including 2 (1.5\%) in group I, 6 (3.8\%) in group II, 36 (11\%) in group III, 27 (37.5\%) in group IV, and 4 (33.3\%) in group V. The rate of occurrence of atrial fibrillation was lower in groups I and II than in groups III, IV and V. Atrial fibrillation was rarely found in coronary artery disease.
