Fine versus coarse atrial fibrillation in rheumatic mitral stenosis: The impact of aging and the clinical significance

Background Atrial fibrillation ( AF ) as the most rhythm disturbance in patients with rheumatic mitral stenosis ( MS ), is classified in to coarse and fine subtypes according to the height of fibrillatory wave amplitude. The aim of this study is to identify the factors associated with the presence of fine versus coarse morphology in patients with rheumatic MS . Methods In this cross‐sectional study, patients with confirmed diagnosis of severe...
