Hi there. Same here, I'm 31 year old male, had pvi Cryoablation 4 weeks ago. Also my rest hr was in the low 50s and now is late 60s, I was also worried about this thinking my fitness level had declined! Also I'm getting a lot of ectopic beats? Is this anything you can relate to?
I was told by my Ep that it is common to have a higher rate after ablation. My heart rate like yours was in the fifties. After my ablation it was in the 80's. Now it has been a year since my ablation my heart has "settled" down and my rate is usually in the 60's.
