Etiology of atrial fibrillation
AF can be associated with underlying cardiac diseases, but it may also occur in otherwise normal hearts.
Common Causes
Complete Differential Diagnosis of Underlying Etiologies for Atrial Fibrillation
As most cases of atrial fibrillation are secondary to other medical problems, the presence of chest pain or angina, symptoms of hyperthyroidism (an overactive thyroid gland) such as weight loss and diarrhea, and symptoms suggestive of lung disease would indicate an underlying cause. A previous history of stroke or TIA, as well as hypertension (high blood pressure), diabetes, heart failure and rheumatic fever, may indicate whether someone with atrial fibrillation is at a higher risk of complications.[1]
| Cardiovascular | Acute myocardial infarction • Congenital heart disease especially atrial septal defect in adults • Coronary artery disease • Heart failure (especially diastolic dysfunction and diastolic heart failure) • Hypertrophic cardiomyopathy (HCM) • Hypertension • Mitral regurgitation
Mitral stenosis (e.g. due to Rheumatic heart disease or Mitral valve prolapse) • Myocarditis • Pericarditis • Previous heart surgery • Dual-chamber pacemakers in the presence of normal atrioventricular conduction.[2] • Restrictive cardiomyopathies (such as amyloidosis, hemochromatosis, and endomyocardial fibrosis), cardiac tumors, and constrictive pericarditis |
| Congenital | |
| Dermatologic | No underlying causes |
| Drugs | Digoxin in patients with vagally mediated AF |
| Ear Nose Throat | No underlying causes |
| Endocrine | Hyperthyroidism • Hypothyroidism • Pheochromocytoma |
| Gastroenterologic | Vomiting |
| Genetic | A family history of AF increases risk by 30%.[3] Various genetic mutations may be responsible.[4] |
| Hematologic | No underlying causes |
| Infectious Disease | No underlying causes |
| Musculoskeletal / Ortho | No underlying causes |
| Neurologic | Multiple sclerosis |
| Nutritional / Metabolic | No underlying causes |
| Oncologic | No underlying causes |
| Opthalmologic | No underlying causes |
| Overdose / Toxicity | Excessive alcohol consumption ("binge drinking" or "holiday heart syndrome") • Carbon monoxide poisoning • Caffeine • Stimulants |
| Post-Op Complication | Surgery,particularly coronary artery bypass surgery • During pulmonary artery line placement and right heart catheterization trauma to the right atrium can result in atrial fibrillation |
| Pulmonary | Hypoxia of any cause • Lung cancer • Pneumonia • Pulmonary embolism • Sarcoidosis • sleep apnea syndrome |
| Renal / Electrolyte | Hypokalemia |
| Rheum / Immune / Allergy | No underlying causes |
| Trauma | Electrocution • Cardiac contusion |
| Miscellaneous | Hypothermia • Fever |
