Yes, although some people take a year, even a bit longer, before they suddenly notice that their HR (heart rate) returns to their previous rate, or to something close to it. Some report HR as high as 90 for weeks after an ablation, some say they were going for hikes a day or two later and had no problems, and that their resting HR was normal. So, it depends on the person.

An HR less than 100 BPM is still considered to be 'normal', provided it is also above 50 BPM. In this case, as I understand it (I could be mistaken), as long as you are confirmed to be in NSR, even if you have an annoyingly high rate near 95, you're still good...technically. But, you have to live under your skin and with your heart, so if it's uncomfortable, you should probably get help, or at least consult someone who knows what's happening and who can assure you.

You are apparently not fibrillating. You have short runs of tachycardia which bears scrutiny, and that is why I urge you to see your EP. But you are well outside your blanking period, and you had only early (typical) short runs of AF while in the blanking period....which is excellent. It's when you begin to fibrillate near the 6 week mark and beyond that the literature I read suggests that the prognosis is not good for a 'successful' ablation. Your runs were all within the first couple of weeks or so, which the same article said bodes well/normal for a great many ablatees. In fact, the pamphlet given to me upon release was by an American heart surgeon who warned that it is perfectly normal to have some minor AF during the blanking period and to not sweat it. The other article I mentioned did warn that it seems that later arrhythmias, say six/seven weeks and later, do not bode well. Early bouts, good, later bouts, probably not good. And so, to address your last question above, quite possibly you have, or your heart has found, some other way to make your heart beat atypically.

So, to summarize, I would agree with your cardiologist because you ARE in NSR. No arrhythmia. Just some tachycardia, which, if it persists and becomes quite intrusive, might stand further investigation and perhaps a 'touchup' ablation. But that decision would come from the experts treating you.
