Why the study?
Does a nitroprusside-induced hypotensive stimulus elicit a different sympathetic nerve activity response in POTS patients compared to controls?
Population

May reflect compensatory sympathetic activation in POTS; hypothesis-generating for autonomic mechanisms without practice implications.
Does a nitroprusside-induced hypotensive stimulus elicit a different sympathetic nerve activity response in POTS patients compared to controls?
POTS patients exhibit an exaggerated sympathetic nerve outflow response to hypotensive stress, which helps maintain cardiovascular homeostasis despite potential sympathetic denervation.
Bonyhay et al. (2004) studied this question.
