Hey, so I'm new here. I'm an 18 year old with ongoing chest pain, faints and shortness of breath, so the latest diagnosis test to try and find the solution was a 24 hour ecg. My doctor said that my heart rhythm was fine, but the range jumped around (when I had pain spells it would speed up or slow down noticeably on the scale but I don't remember the numbers). I have no idea what this means, does it sound like its leading towards a diagnosis of why my heart can hurt so bad? Or does anyone even recognise my symptoms and have any suggestions of what it could be?
