Tachycardia following Ablation

My ablation (2nd) was performed in November and immediately after that I experienced an increase in my resting heart rate from 65-70 BPM to low/mid 90’s BPM.
I’m back in sinus rhythm but this week I had my 90 day follow up that included a EKG. My EP says that tachycardia, which I now have is not unusual after an ablation. So the fix now is to have a cardioversion and if that doesn’t correct it then another ablation will be done. Anyone here have a similar experience? Thanks
