Hi, my name XXXXXXX! I m a 16 year old female. I ve been having heart complications for about 5 months. I ve been to 5 doctors, 4 being cardiologist . No one has had an answers yet. My symptoms: chest pain , paplimations, heart pounding, oxygen drop(lowest 84), blood pressure scaling up & down, cramps everywhere, small busted blood vessels, head aches, dizzy, chest pains with just left arm going numb(as if it fell asleep), low potassium , nausea, shaking when hearts beating fast. Some of the doctors have said they THINK I may have any of the following: SVT, PACS, WPW , extra wire in heart. But that s it. I have my second heart monitor on now. But this new doctor isn t telling me anything. My old cardiologist said he found early & extra heart beats. Also on my last 2 EKGs, it showed possible left atrial enlargement. The doc showed me where that was & that s where I have the worst pains. But on my echos before those EKGs, my left atrial was fine. If you have ANY answers/ideas please let me know! I m ready to get back to sports & a normal life!
