I am a 34 year old with a history of chest pain, PVCs, lightheadedness, tremors, migraines, heat/cold intolerance. I was diagnosed with POTs after I failed a tilt test. I have had practically every test done, and I just had an angiogram to rule out a coronary blockage. Since the angiogram, I have been feeling very faint. I called my doctor and he said my symptoms are not due to the angiogram. I am wondering if the invasiveness of the procedure, along with the sedation and contrast dye have cause a bad POTs syndrome flare up?? Has anyone had a similar experience?
