hi katiev i replied in your other thread where you mentioned this.
but i had it done years ago, to fix WPW, Wolf Parkinson White Syndrome. is that you have, it sounds like it.
if you do, WPW is the only fully curable / treatable heart condition to have , so you are lucky. one in ten people have WPW, and one in ten of THOSE people never have any symptoms, the only reason i knew i had it was cause i had a EKG taken for generic pre-college health check, and EKG can sniff them out easily.
with ablations, the younger you are, the easier it is on you and better chance of success. i had it done when i was 17-18, and you being 19 is a huge plus for you. as you get older , the veins/ arteries become less elastic.
i was knocked out cold and when i woke up hours and hours later everything was fine, no pain. you arent allowed to eat before hand, and when you wake up it will be something close to 18-24 hours you will have gone without food, so you will be quite hungry. this may get a little graphic...but I remember the first thing i did was go to pee, i had to roll the saline/ med drip unit with me. mid - pee i felt a warm sensation on my left foot, and i thought to myself "i cant be peeing on my leg, wtf?!" and what had happened was that the entrance site to the leg artery, opened up and bled a little bit. sort of scary at first but it was nothing. on the way home from the hospital, the top of my knee to halfway up my leg felt like pins and needles. i told my mom, who then freaked out, and called the doc. turns out some blood escaped and pooled in a pocket, sort of like a black and blue. it too was normal and would go away quickly.
also dont be surprised when you wake up that most of your pubes are shaved, they need to do that to clean the entry sites.
my friend also had WPW and went in for the procedure. his experience was vastly different because he was afraid to be put under and thought it would be cool to be awake for it. it turned out to be the most horrificly painful experiences of his life, and in the end , they failed. so now he has to go back in and get it down and he wont venture near a hospital because of his newfound hatred and fear of them and doctors.
