Non-valvular atrial fibrillation should first try to be converted to a normal rhythm by treatment, difficult to convert with medication to control the ventricular rate, assess the risk of thrombosis, and anticoagulation should be performed if necessary.
Common causes of non-valvular atrial fibrillation include hypertension, coronary artery disease, hyperthyroidism, pulmonary artery disease, and electrolyte metabolic disorders. If the primary cause can be clearly identified, the primary disease should be treated as early as possible to prevent recurrent episodes of atrial fibrillation.
For the treatment of atrial fibrillation, some can terminate the attack on their own without special intervention, some need to use drugs or electrical cardioversion therapy, drugs are often chosen amiodarone, some special atrial fibrillation such as paroxysmal atrial fibrillation, you can assess the patient’s condition to consider whether to carry out radiofrequency ablation therapy, permanent atrial fibrillation, radiofrequency ablation is poorly effective, generally to control the heart rate and prevention of thrombosis is given priority to.
If surgery is not possible, long-term atrial fibrillation is mostly fast ventricular rate, need to apply β-blockers to control the ventricular rate, such as metoprolol. For permanent atrial fibrillation, CHA2DS2-VASc score is needed to assess the risk of thromboembolism. If the score is greater than or equal to 2, oral anticoagulant therapy is needed, such as rivaroxaban and dabigatran.
The presence of atrial fibrillation should be treated as soon as possible in the cardiology department of the hospital.
