The current treatment strategies for atrial fibrillation are mainly pharmacological and non-pharmacological. (1) To restore and maintain sinus rhythm, such drugs mainly include amiodarone (trade name: Kotarolone), sotalol (trade name: Stavrosol), propafenone (trade name: Eflorn, cardioplegia), mirexazine, etc. The side effects of long-term use of drugs to restore sinus rhythm are obvious or even increase the mortality rate; (2) To control the rapid ventricular rate during atrial fibrillation, such drugs mainly These drugs include digoxin, beta-blockers (e.g., betalactam), calcium antagonists (e.g., Hersinol), etc. Controlling the ventricular rate can improve the symptoms but not the prognosis, and the risk of thromboembolism cannot be avoided because atrial fibrillation still exists; (3) anticoagulation therapy for patients at high risk of thromboembolism is a very effective and important treatment. The shortcoming of anticoagulation therapy is the need for frequent blood tests to reduce the risk of bleeding due to excessive anticoagulation therapy or loss of prophylaxis due to insufficient anticoagulation. 2, non-pharmacological treatment mainly includes (1) electrical resuscitation therapy: is through the method of direct current electric shock, so that atrial fibrillation back to sinus rhythm, its advantage is the high success rate of conversion, the disadvantage is the need for hospitalization and does not have the effect of maintaining sinus rhythm; (2) catheter radiofrequency ablation: this interventional operation without incision has been carried out for more than ten years in the larger cardiac centers at home and abroad, has been proven to maintain the ability of sinus rhythm (3) surgery: At present, it is mainly used for patients with atrial fibrillation who need to undergo cardiac surgery due to other heart diseases. Minimally invasive surgery assisted by thoracoscopy developed in recent years is effective in isolating the pulmonary veins, but it is difficult to intervene in lesions outside the pulmonary veins, and the surgical trauma is greater than that of catheter radiofrequency ablation, and expert consensus at home and abroad recommends that surgery is not suitable as the initial treatment for atrial fibrillation. Atrial fibrillation due to certain diseases such as hyperthyroidism, acute alcohol moderate, drugs, and stress may disappear on its own after elimination of the cause, but it mostly still persists.
