Regarding whether atrial fibrillation can be completely cured, it essentially depends on the definition of being completely cured. If the criterion is complete cessation of medication, then many patients cannot achieve this. However, if the standard is conversion of atrial fibrillation back to normal sinus rhythm, then it is achievable for many patients, such as those with paroxysmal atrial fibrillation, who suffer from recurrent episodes and do not respond well to medication. In such cases, radiofrequency ablation might be attempted, and there is a high likelihood that after the treatment, the rhythm will convert to sinus rhythm. In this sense, some people can be considered cured. However, whether anticoagulation therapy can be discontinued depends on their thromboembolic risk score. This means that even if atrial fibrillation converts to sinus rhythm after radiofrequency ablation, some patients still need long-term anticoagulant medication. Therefore, from the perspective of discontinuing medication, such patients with atrial fibrillation are not considered cured.
