WHY??

Im 14 year old male and was diognosed with SVT about a year ago. I didnt really care about the crappy disorder untill a few months ago. I got the Catheter ablation surgery to get rid of the SVT, but when my cardioligist did the surgery, he said he found that my SVT was more severe than he thought, and could not finish the surgery. So I thought Oh well thats great. He said to stay on my medicines, and we will do another surgery soon. Well about a week ago, I was having these weird blackouts. I wouldnt pass out to the ground, but I would have these mental blackouts. I wouldnot know where I was or what I was doing for a few seconds. I told my doc and he wanted me in the hospital right away. So I thought ohhh myyyy ggggooooddd. I hate hospitals. I went in to the hospital and stayed there for 3 days, while they were trying to track this blackout problem down. First they thought I had a certain type of seizure. Then they realized that my heart was doing this. During a test at the hospital, My at rest heart rate went from 55 beats a minute, to 160 beats a minute within 4 seconds. The team of cardioligists said then that my heart would raise my blood pressure, causing me to be in a unconcious state. I finally got out of the hospital, yesterday, and i am going back on the 16 of june for the next surgery. If this surgery doesnt work, then my doctor will send me to a different state for a more advanced surgery.

Has anyone had these blackouts with SVT before. I dont want to feel alone here. My whole family thought I was like going to die or something. I hate SVT disorder. Its so stupid. Its not life threatning, but its not, non harmful either.
