The treatment of atrial fibrillation, first and foremost, should actively seek the primary disease and inducing factors of atrial fibrillation, and make corresponding treatments. Currently, the treatment of atrial fibrillation mainly includes two types: one is drug treatment. Since patients with atrial fibrillation have a higher incidence of embolism and may have a history of embolism, valve disease, hypertension, diabetes, older patients, left atrial enlargement, and coronary heart disease, which can increase the risk of embolism, therefore, such patients should be advised to undergo long-term anticoagulation treatment. Another type of drug treatment is to control the ventricular rate. When drug treatment is ineffective, surgical treatment can be chosen, and the main surgical treatment currently is radiofrequency ablation.
