So I had WPW (I’m not clear on the different causes and types). The ablation stopped the “extremely high heart rate for extended periods” which was the main concern.
My understanding (as a teenager) was that the main risk with the heart sitting at >250bpm for hours on end was a clot. But even that was more a later in life concern.
I still get some uneven rhythms at times - beat, beat, semi pause, beat kind of thing. I was told that this is due to the fairly unsophisticated method used to remove the pathway, whereas today it’s much cleaner and tidier.

Ooh interesting!
I had an ablation 10ish years ago and was told the AF would probably return and to keep an ear out for it after 5 years. I get very occasional irregularities now but nothing sustained so haven't gone back for anything. So it's not inevitable that it comes back? (It was explained to me as the erratic nerves finding new routes/connections over time.)
