The cardinal signs of these conditions are low blood volume, reduced orthostatic cerebral blood flow, increased orthostatic sympathetic outflow, and in a subset of patients, elevated angiotensin II mediated reductions in Neuronal nitric oxide activity. Parasympathetic withdrawal is the consequence.Anonymousnoreply@blogger.com
