Q: What are the treatment strategies?
A: There are two main treatment strategies: cardioversion, which is the attempt restore the normal “sinus” rhythm (“rhythm control strategy”) or control of heart rate ("rate control strategy”). The rhythm control strategy, if effective, allows minimizing the symptoms and risks described above. It also enables discontinuation of the administration of anticoagulant drugs. The maintenance of sinus rhythm, however, is often difficult or impossible, especially when ultrasound shows an increase in the diameter of the atria. The possibilities of therapy are focused on the use of antiarrhythmic drugs (pills) or radiofrequency ablation.
