Reducing atrial fibrillation episodes is mainly done by removing the causes and triggers, medication, electrical cardioversion and catheter ablation. 1. Removal of causes and triggers: Common causes of atrial fibrillation include hypertensive heart disease, coronary artery disease, hyperthyroidism, etc. If there is a clear cause of atrial fibrillation, it should be actively treated. In addition, alcohol consumption, smoking, and fatigue can be triggering factors for atrial fibrillation, and these triggering factors should be avoided. 2. Drug therapy: Drugs such as amiodarone, propafenone and other drugs for drug resuscitation, digitalis preparations, calcium channel blockers and other drugs to control the ventricular rate can help to reduce the occurrence of atrial fibrillation. 3. Electrical cardioversion and catheter ablation: In the case of ineffective pharmacological cardioversion or more serious atrial fibrillation, electrical cardioversion and catheter ablation can be used to restore and maintain sinus rhythm. In order to minimize the occurrence of atrial fibrillation, we should consult a doctor in time, identify the cause of the disease, actively treat the primary disease and remove the triggers, and choose the scientific treatment under the guidance of a physician.
