@camy33x I'm sorry this affects you thusly. The bottom lines for heart arrhythmias that are NOT immediately life-threatening: if they don't bother you much, if their treatment or management isn't urgent, then you really need to do pretty much nothing. In the case of AF, stroke is the great immediate risk, and a competent authority will urge you (strongly) to take a direct-acting oral anti-coagulant like Eliquis (apixaban) or Xarelto (rivaroxaban). But, if you are asymptomatic, and still in the early stage (paroxysmal), and you feel well, many people live that way for years happily. They may take two or three metoprolol tablets when their heart goes into AF and the rate is fairly high, say 120 or higher. That's to keep the heart from fatiguing at the typical AF rate with 'rapid ventricular response', usually 120 and up.

So, there is no cure for AF. You can treat it, but once it's diagnosed it's a permanent disorder. We treat it in a palliative way, meaning we try to keep it from 'spreading' and from getting worse, and we try to suppress the nastiest symptoms. Again, millions get used to it, or they get in line for an ablation, or they suppress it with drugs. There's no one-size-fits-all about AF.
