Hi Angel, I understand exactly what you're talking about
. I'm recovering at the moment from the procedure having spent the past 20 years plucking up the courage! I'm 30 and from what I know, it's exactly the same procedure as if you're 17 or 18. I've had adenosine and lived with the fear of attacks all my life and it's an incredible relief to have gone through the procedure at long last. I admit, It's very scary having it done but the thought of living with the condition for the rest of my life was worse to me so i decided to do it.
Yes, you're awake but they don't stop your heart. They send electric signals in to try and kick start your condition to properly diagnose it. Once they've brought your svt on, they return it to a normal rhythm and burn away the part of your heart that's causing the electric short circuit. I was sedated and had morphine because my leg veins were hurting a fair bit during the procedure so was pretty out of it by the end. It lasted about
2 hours from start to finish. The doc came and told me at the end that I'm cured and the chances of the condition returning are next to nothing so it was well well worth it, even it was a frightening experience. I left hospital the next day and now i'm up and about
If I were you, I'd go for it but it's definitely something you have to get your head around doing first. The most important thing is to get a good electrophysiologist who has done lots of ablations in the past - I spent a while finding out about
good places in the UK and eventually got my GP to refer me to the Royal Brompton in London. The care was superb, as was my doctor who is very respected worldwide in this field.
If you have any questions, I'd be more than happy to try and answer them as I know how helpful I found this site when I was trying to make my mind up!
