The diagnosis of<unk>  depends on the overall function of three autonomic functions – cardiovagal, adrenergic, and sudomotor. A diagnosis should, at a bare minimum, include measurements of blood pressure and heart rate while lying flat, and after at least 3 minutes of standing. The best way to achieve a diagnosis includes a range of testing, notably an autonomic reflex screen, tilt table test, and testing of the sudomotor response (ESC, QSART or thermoregulatory sweat test). Additional tests and examinations to determine a diagnosis of<unk>  include: Valsalva maneuver Tests to elucidate the cause of<unk>  can include: * Evaluation for acute (intermittent) porphyria. * Evaluation of cerebrospinal fluid by lumbar puncture\ Vegetative-vascular dystonia Particularly in the Russian literature, a subtype of<unk>  which particularly affects the vascular system has been called vegetative-vascular dystonia. The term "vegetative" reflects an older name for the autonomic nervous system: the vegetative nervous system. Similar form of this disorder has been historically noticed in various wars, like Crimean war and American civil war and among British troops who colonized India, this disorder was referred to as "irritable heart syndrome" (Da Costa's syndrome) in 1871 by American physician Jacob DaCosta.
