Hello and welcome to HealingWell.
Radiofrequency ablation is acceptable first-line therapy for many arrhythmias including your rhythm. However, what I am not sure of is what the next choice of treatment would be if your sx have come back.
Please be your own best advocate and ask if you need further tests, why your resting heart rate has increased after the ablation and what does the cardiologist suggest is the next step in dealing with your problem.
If you are not satisfied with the answers you receive do consider looking for a second opinion.
I hope another member will be along that has experience with this same type of issue.
I am so glad you found us.
