Clinically there is no such thing as a nemesis for atrial fibrillation, and patients need to take medication, surgery and other treatments under the guidance of their doctors. 1. Medication: Usually, patients with valvular disease can be treated with anticoagulants such as warfarin as prescribed by the doctor, and the International Normalized Ratio (INR) needs to be detected and controlled at 2.0-3.0. Patients with non-valvular disease can also use anticoagulants such as dabigatran etexilate, rivaroxaban and apixaban. And patients can also use rhythm control drugs such as propafenone, quinidine, and amiodarone in combination. At the same time, patients can also control the ventricular rate through beta-blockers such as metoprolol and atenolol or calcium channel blockers such as verapamil and diltiazem. 2. Surgical treatment: patients can choose to undergo cardiac radiofrequency ablation, surgical maze surgery and left ear blockage according to their condition. 3. Other treatments: If atrial fibrillation occurs in myocardial infarction, extremely fast heart rate, heart failure, etc., it can also be treated by physical therapy such as electrical cardioversion. It is recommended that patients with atrial fibrillation avoid unauthorized use of drugs, the use of all drugs should be applied under the guidance of a doctor, and timely medical treatment to take standardized treatment.
