The relationship between chronic atrial fibrillation and reduced pulmonary function in cases of preserved left ventricular systolic function

The purpose of this study was to investigate the relationship between chronic atrial fibrillation (AF) and reduced pulmonary function. Eighty-six chronic AF patients who were enrolled from annual health examination programs were studied using echocardiography and pulmonary function tests (PFT). Echocardiography and PFT matched for age, gender, and year performed were selected by the control group who had normal sinus rhythms. Patients with ejection fractions
