arrythmia

i was diagnosed with postural orthostatic tachycardia syndrome a few weeks ago . but i am not convinced i have it. My symptoms don't come when i stand up. They come randomly throughout the day. My cardiologist put me on beta blockers for the fast heart rate which made my low heart rate even worse to around 30. I had also gained ten pounds in 3 days while on the beta blocker and my legs and ankles swelled up so i stoppes taking it. When i told him about this he kind of blew me off and said that all my pot syptoms (symptoms) had seemed to go away.I get bad chest pain and shortness of breath when i get both tachy and brady.  When my heart rate gets low At rest my heart rate goes down to around 40 but during the day my heart rate can spike to over 160 at rest. Also just walking up the stairs my heart rate goes from 45 to 180 then it drops right back down. Also my blood pressure is normally 90/60 but for the past month it has been consistently 140/110 with occasional readings of 200/150. when my blood pressure gets above 150 i start getting bluried vision, ringing in my ears and a bad headache. Sometimes i get crushing chest pain to.  I am only 17 and i dont know what to do. should i see another doctor? What could it be and how can it be fixed. Also some past medical history within the past 2 years i have been in septic shock twice, 2 DVTs, pulmonary embolism, chronic osteomulitis in my foot and 21 surgeries to get rid of it, 2 collapsed lungs with chest tubes, went into respitory arrest after a foot surgeryand 2 picc line infections. Could my past history contributed to the problems i am having now?

Sorry you haven't gotten any replies, but your post/case is very complicated and I think well beyond the experience of most of us, and thankfully so as you have suffered too much.

The best path is working with a cardiologist to determine if there are any heart conditions that should be treated.  

Your statement:  "he kind of blew me off and said that all my pot syptoms (symptoms) had seemed to go away." lost me and may have done the same to others.   Whatever it means, I remain of the opinion that a cardiologist is the way to find an answer.
