hi my name is lisa im 22 years old and i found out a couple years ago i have svt. since then i have been put on 2 different kinds of medication and there has been a few times i have blacked out feeling dizzy. sweaty, light headed and short of breath. by the time i get to the hospital all my vitals and everything else are good the most recent time i got blood taken and my doctor said my white blood cell count was high. could this be related to my svt?
