Hello, My name is Morgan. I am a 21 yr. old female 5 7, 135lbs. I have Wolf-Parkinson-White Syndrome and am not currently seeking treatment, nor taking medication for it. I ve had to wear a Holter Monitor in the past and never heard back from the cardioligist, which im assuming means everything looks ok. I was diagnosed about 2.5 years ago. Fast forward to present time: Im currently experiencing a rapid, pounding heartbeat, dizziness apon standing, anxiety and slight chest tightness. Blood pressure is 157/79. Im just wondering if this sounds serious or if not, is there any treatment options I can do myself w/o medical help. Thank you.
