I am 24... for years I have had a multitude of symptoms but until recently a cardiologist is finally taking me seriously. I have a constant rapid heart rate, constant high blood pressure, (last time was 163/120 on one arm and 170/100 on the other) I am not over weight, often I get chest pains and numbness in my left arm, Often times I get dizzy with some episodes of syncope. The doctor says my symptoms are "troubling" but cant come up with a diagnoses so far. They have done an echo... with a mitral valve prolapse... ekg, event monitor, halter monitor, chest xrays, alot of blood tests, urine tests... I also have kidney stones all the time, vitamin d deficiency, Urine tests show + metanephrines and + catecholamines but a CT scan was negative so he doesn't want to "jump to a diagnoses of pheochromocytoma" because its rare.I have done different doses or propanalol and labetolol none of which have reduce blood pressure or helped the tachycardia... I am so frustrated and worried because he said some symptoms I have are associated with sudden death.. I have an aunt who died suddenly but no autopsy was performed due to her religious "rules"... what is next... what do I do from here? He(my cardiologist) suggested going to Mayo, but really is that what its going to take to get a diagnoses? He also said everything easy has already been ruled out... please help!!! Oh I guess I can add that my "baseline" heart rate is never lower than 120
