@veronica0127 Hi, based on what you have just mentioned my experience with HR has been very similar. In the weeks and months following my ablation on 2/14/23, my resting heart rate was even a little higher, averaging around 80-82. It would always go into the low 100's as soon as I was up in the morning and walking around, which I was told was completely normal and expected. I am now 3 years post ablation, and my resting HR has settled in the low 70's but always goes up when I am active and moving around. I read the post by @gloaming who gave a great explanation with more detail of what you should be expecting following your ablation. Since it has only been 3 weeks for you, I would expect that you might feel a bit tired on occasion as your body recovers, but that should ease off as you completely heal from the procedure. I feel very fortunate to have had an ablation early in my Afib diagnosis and which so far, has continued to be successful. I wish you the same.
