Clinically, no obvious signs of atrial fibrillation have been found, and there is no way to stop an atrial fibrillation attack before it occurs. The only way to manage atrial fibrillation is to detect it early and treat it early. Treatment mainly includes resumption of sinus rhythm, prevention of thrombosis, surgical treatment and treatment of the primary cause of atrial fibrillation. 1. Early detection: Some patients with atrial fibrillation may have no symptoms or mild symptoms that do not attract the attention of the patient, therefore, it is necessary to go to the hospital for examination through regular physical examination or when palpitations (accelerated heartbeat, often accompanied by panic) and other discomforts occur in order to detect atrial fibrillation at an early stage. 2. Repeat sinus rhythm: Including drug rewarming and electric rewarming. Commonly used drugs are amiodarone and propafenone. Electrical cardioversion is mainly applicable to atrial fibrillation episodes when the ventricular rate is very fast, accompanied by a significant drop in blood pressure or the emergence of acute left heart failure, the patient’s hemodynamic instability, or after drug treatment still have obvious symptoms. 3. Prevention of thrombosis: the main treatment is to apply anticoagulant drugs, commonly used are warfarin, dabigatran etexilate and rivaroxaban. 4. Surgical treatment: including radiofrequency ablation and open surgical labyrinth surgery. 5. Treatment of primary causes of atrial fibrillation: there are many diseases that can cause atrial fibrillation, such as organic heart disease, pulmonary artery embolism, hyperthyroidism, and water-electrolyte disorders, etc. Actively treating the primary causes of atrial fibrillation plays an important role in controlling the occurrence of atrial fibrillation. If you feel unwell, it is recommended that you consult a doctor in time to avoid any delay in your condition.
