Patients with atrial fibrillation cause tenderness of the feet, which is related to the reduced ejection of blood from the heart. Anticoagulants, rhythm-control drugs, and ventricular-rate-control drugs can usually be taken. 1. Anticoagulants: e.g. warfarin sodium, which is effective in preventing thrombosis and requires regular monitoring of the INR (International Normalized Ratio, which is indicative of routine coagulation). 2. Rhythm-control drugs: for example, propafenone, amiodarone, etc. These drugs can effectively control the heartbeat rhythm, to achieve the purpose of reversal of success, when the heartbeat rhythm back to normal, can effectively relieve the body of symptoms such as fatigue, weakness. 3. Ventricular rate control drugs: If tachyarrhythmia occurs, it is necessary to orally take beta-blockers as soon as possible, such as the commonly used atenolol, metoprolol and so on. 4. Treatment of primary diseases: For diseases that cause atrial fibrillation, such as hypertension, coronary heart disease, heart valve disease, etc., it is necessary to apply antihypertensive drugs, improve the blood supply to the heart, and treat heart valve lesions and other active treatment of primary diseases. Atrial fibrillation patients taking the above drugs should be under the guidance of a doctor, to avoid unauthorized use of drugs caused by adverse reactions.
