Hi salla - yes I have had an ablation procedure done & mentioned it on here a couple of years ago, see my posts on this link:

However, the 'old' symptoms recently reappeared, but since starting medication (one pill a day) to control the angina pain & arrhythmia, I feel very much better! Even able to run up the stairs again, without getting puffed out!
Everyone is different, but I'm sure you will be absolutely fine, so think positive & let us know how you get on.
Take care.
