Atrial fibrillation has no self-healing trick, atrial fibrillation in general can not be self-healing, only the early mild paroxysmal atrial fibrillation can not be dealt with. The treatment of atrial fibrillation is mainly to treat and control the primary disease, and long-term comprehensive management of the disease. Commonly used treatments include drug therapy, catheterized radiofrequency ablation, and electrical cardioversion. 1. Drug therapy: drug therapy generally includes drug anticoagulation, drug resuscitation and drug control of ventricular rate therapy. Commonly used anticoagulant drugs are warfarin, drug resuscitation generally use propafenone, amiodarone, etc., and control of ventricular rate commonly used propranolol, digoxin, etc.. It is necessary to be alert to drug contraindications, such as pre-excitation syndrome combined with atrial fibrillation, second-degree or high degree of atrioventricular block should not be used digoxin and so on. Please use the medication under the guidance of the doctor, do not use the medication by yourself, and go to the hospital immediately if there is any adverse drug reaction. 2. Catheter radiofrequency ablation: it can cure atrial fibrillation, and it is suitable for patients with atrial fibrillation accompanied by obvious tachycardia, chest tightness and other symptoms, and the drug treatment is ineffective. 3. Electrical cardioversion: It is suitable for patients who are ineffective in drug treatment and have acute heart failure and significant drop in blood pressure. The safety and success rate of this treatment is high. What kind of treatment should be applied should be determined by professional doctors combined with the patient’s own situation, and it is recommended to consult the doctor in time to avoid delaying the condition.
