[|AI|]  Hello. Thank you for your question and welcome to Chat Doctor. I understand your concern. An established diagnosis of chronic, persistent atrial fibrillation, mandates rate control and anticoagulation. During atrial fibrillation, the reason people have strokes, are the thrombi (clots) formed in a fibrillating, non-functional atrium. But this problem is solved with a proper anticoagulation and keeping the international standardized ratio (INR) between 2.0 - 3.0. On the other side, rate control can be achieved with various Chat Doctor.  First, the heart rate should be kept under 90 beats per minute. It is not the risk of strokes when the heart rate goes up, but the risk that every atrial fibrillation beat (which goes up to 400-600 beats per minute) may be transmitted to the ventricle and such a rate for the ventricle produces life-threatening ventricular arrhythmia. That is why
