Thank you for your reply! I went to a specialized cardiology hospital in Canada where I saw a cardiologist (urgentologist) - I don't think anyone there was present because of non-heart conditions.

I did explain to the doctor about my family but she did not seem worried. I am wondering what other test they could be doing? Since I am not insured here I can only go see a cardiologist at the emergency, but I can take an appointment when I am back home.

I feel that the only test I could be doing is an EKG while running and a CT scan. Is it worth going to the Emergency again? Also, I have been so dizzy for months and again, the brain MRI was good, so I am wondering if that could come from that...Again that could also be from my mysterious disease.
