@kirbymaree Perfectly understandable to be in dread. I can only answer for me...I know me best. This guy, me, I hate operating from a position of no knowledge or poor understanding. I gotta know! So, despite having to read or watch videos explaining what all the bad stuff might be ahead, I have to begin chewing on possible alternative treatments or strategies. I can't do that honestly without knowing more than I understand at the moment, so I begin the laborious process, sometimes going down rabbit holes until the wee hours. Eventually, I can call it a day and fall asleep letting my mind mull over what I now understand.

I commend this orientation to your own health because it tends to be productive and it tends to keep you in the realm of power or potency. You get to question knowledgeably, not argue, but to ask why this and not that? If it must be this, you will at least have learned ahead of time that it might be the alternative your health provider wants to try first.

I developed atrial fibrillation (AF) near the tail end of a 10 km maintenance run. I lost steam suddenly, legs went heavy, and I began breathing much harder than I should have been. I sat on a curb, tried to let my heart calm, but I ended up in the local ER and soon learned I had a new diagnosis of paroxysmal AF. Paroxysmal means it comes and goes on its own, you don't need medical intervention, at least not in an ER. In your case, it might be AF, or it might just be PACs (premature atrial complexes, often a precursor to AF...you'll develop AF in time often, not certainly, but often you do go on to AF.

Whatever it is, shouldn't you know for your own sake? And wouldn't you like to know you have a specialist looking after you, who knows of you and your condition, and who offers you a way ahead....something to build optimism instead of dread?
