Heave you ever herd of inappropriate sinus tachycardia? How hard is it to diagnose? Think I've had it for 13 yrs. Diagnosed as anxiety & deperssion.

It means w/out cause. It's that specialists cannot find a physiological cause that is 'inappropriate' in the dx. A person can also suffer emotional problems, but they could be tangled up w/ the heart too. Try to urge your doctors to consult and take the heart issue into consideration when prescribing psych meds - many can have side efxs of cardiac malfunction and you want to avoid this risk. Work as a team, ok? Best!
