This is just my guess based on what I have learned over the years and from trying to incorporate some commonality I see posted anecdotally by people discussing AF and ablation recovery:
a. Each of us is unique and responds to stressors in his/her own way. Sometimes, a lot of the experience is common, often some of it is not;
b. Most hearts are going to be cranky after an ablation. Leaving aside what was going on in the weeks prior to an ablation, some of which might have been rather oppressive, the operation is itself a stress, and it leaves the heart's septum and lesion locales irritated and damaged;
c. A great many report elevated HR for weeks, even months, after an ablation. Some report that they finally noticed their heart returning to a decent low HR a year later. Wow!;
d. Any exercise during the blanking period may be too much, too soon. Your heart may indicate as much by its rhythm and pace. If the rate slows, say by next morning, then it's probably fine. Don't forget hydration. We get home and get busy, answer a call or return one, and next thing you know you're brushing your teeth in pajamas You could add electrolytes to that; and
e. A heart can be in AF with rates well below 100 BPM. So, if you're worried, use a Kardia or a smart watch not more than about 4 years old now (for best tech and software), and take multiple readings over 15 minutes, including during the activity, to see any indications of arrhythmia or 'undetermined' reading, which these devices will sometimes show when they can't quite bring themselves to fall on the side of the fence where AF lies, but it's still wonky.
