Prolonged atrial fibrillation can have many consequences, the most serious being cerebral infarction due to dislodged blood clots, and prolonged atrial fibrillation can also promote an increase in heart failure. For people with atrial fibrillation, the main thing is to prevent embolism as well as to control the ventricular rate and prevent the aggravation of heart failure symptoms. In terms of medications, to prevent such consequences, it is usually necessary to apply warfarin or rivaroxaban to prevent the risk of thrombus dislodgement, as well as beta-blockers and digoxin to control the heart rate and prevent the exacerbation of heart failure symptoms due to excessive increase in ventricular rate. In case of idiopathic atrial fibrillation or atrial fibrillation with indications for surgery, radiofrequency ablation surgery can be chosen for the radical treatment of atrial fibrillation.
