I had SVT during exercise for decades and, while it was disruptive, I learned to manage it. At some point about 25 years ago I started getting SVT's during stressful times at work. At that point, I saw an electrophysiologist and scheduled an ablation which worked very effectively for a long time.

I only recently had a second ablation which seems to have calmed the SVT and AFIB events even moreso (they had slowly started to recur over the years after my first ablation). I read a lot about the new pulsed field ablation (PFA) techniques prior to having mine and it did not disappoint (my doc used a Boston Scientific PFA tool). I was out doing 7 mile hikes at elevation with no issues only 9 days post ablation. If you have SVT, don't fret. These new techniques should help fix your problems.
