I have connective tissue disease. my chest x-ray showed slightly enlarged pulmonary artery. the symptoms are occasional sob, heart palpitations, bad dizziness andintermittent chest pain. the symptoms come and go to extreme. i am having tte next. cause?

Scleroderma : Scleroderma comes to mind when you attach all those findings ask your rheumatologist.

Tough: The options are so big, hard to answer. Perhaps the symptos are not cardiac but a combination of anxiety and cardiac working together? How's sleep? Try prilosec, won't hurt, see if reflux contributing. Is dizziness related to blood pressure? Are you tall, linky, see marfans' syndrome. Did u mean tee for the next test? It's complex but treating reflux, anxiety and mood during workup may help.

CTD : Connective tissue disease(ctd), an autoimmune disease, can attack almost every organ in your body. In advance disease, pulmonary hypertension, cardiomyopathy, pericarditis, even coronary syndromes( less likely) can complicate the disease. Examples: lupus, polymyositis, scleroderma and mixedctd. Agree with tee. Close follow up necessary.
