Hi. Depending on the EP, what they know and think about your circumstances and health, their experience ablating elderly patients, especially with your particular health concerns, it may not be a great idea to ablate you. Next door, another EP, maybe more experienced, different 'upbringing', might think you're the perfect candidate for an ablation.
You are still in the paroxysmal stage; it limits the time in AF by reverting to NSR and stays in NSR for hours or days. THIS IS LIKELY TO BE THE BEST YOUR HEART HEALTH WILL EVER BE. As a progressive disorder, your heart will continue to decline until you are in persistent AF, then long-standing persistent AF, and finally permanent. This is not absolute....cases vary widely between individuals. Some progress rapidly, some take decades. But, almost every one progresses. So, today, actually yesterday, was the best time to have an ablation to help to stop any morphological 'remodeling' that the heart undergoes the longer it is in arrhythmia, especially in AF.
This is just my philosophy, and it is probably not going to be affirmed by every responder. I do know that ablation is 'the gold standard of care' for AF patients. Drugs can work, even very well, and even for a very long time. However, they tend to get used to by the heart, especially since it's always progressing in its AF journey, and you'll need more of the same drug or have to resort to another, and then another, and finally amiodarone or get a pacemaker if your ventricles try to keep up all the time with beats running in the 140-200 range, which so many AF patients experience.
It's a complicated subject and well worth your time with self-education. But as you age, as your heart's condition deteriorates, ablation will slowly be drawn out of reach for you. Either get it done now, even if you have to seek another EP's services, or expect to have a difficult time with drugs and perhaps morphological changes such as valve problems, vessel enlargement, more complicated and additional arrhythmias, and finally heart failure ( a horrible term that doesn't mean what it says, but that's what the medical community uses...).
@gloaming A sincere thank you for your thoughtful, informative philosophy. There is a lot to consider and discuss with my doctors. I have had concerns that the process of evaluating different medications is affecting my heart health. So far, my echocardiogram and PET Stress results are good.
