For young people who develop atrial fibrillation, it is important to go to a specialized hospital to find out the cause of atrial fibrillation, such as primary heart disease, congenital heart disease, or atrial fibrillation secondary to other diseases that cause arrhythmias, and the key to solving the problem is to treat the cause after identifying the cause of atrial fibrillation. Atrial fibrillation can be controlled with medications such as warfarin, which can be taken regularly, but coagulation must be monitored. Atrial fibrillation can also be controlled by taking anti-arrhythmic drugs, such as amiodarone, or beta-blockers, such as metoprolol tartrate and metoprolol succinate, etc. The Chinese medicine heart-stabilizing granules also have a certain effect on atrial fibrillation. Intractable atrial fibrillation can also be treated by surgery, but no matter what approach is taken to treat atrial fibrillation, it is important to clarify what the primary cause of atrial fibrillation is.
