Yes. I had one at age 30.
I had suffered from palpitations, dizziness and exhaustion my whole life, fobbed off by GP’s as anxiety. During Labour, I complained about the palpitations and the lovely anaesthetist diagnosed me with AV node re-entrant tachycardia (basically an extra electrical pathway in my heart).
I went in to hospital for an ablation five months later. Was told before hand that if the issue was on the right hand side of my heart I would be sent home in a few hours. If it was on the left side, then they would have to pierce through the septum to ablate, so would have to keep me in for 2-3 days.
Luckily, mine was on the right, so done and dusted in about 40 minutes (for the procedure) and two hours-ish in recovery (they let my partner and baby in the recovery room with me straight away since I was breastfeeding exclusively).
I found the procedure slightly painful but I was only given tiny puffs of Valium up my nose, due to the breastfeeding, so there is probably better pain relief available generally.
Afterwards, the difference in the way my heart beat was instantly different. I could stand up and not get palpitations! I could get shocked and not get palpitations. It was great. My energy levels (after the first 4-5 days) we MASSIVELY improved and I literally couldn’t believe how easy life was compared to previously! I hadn’t realised the tiredness I had been feeling my whole life was abnormal.
Anyway, I would definitely recommend getting this procedure. It’s such a small thing yet so life changing!
