Abstract:
PURPOSE: Initial orthostatic hypotension is typically associated with active standing and normal autonomic function. Some adolescents in the present study displayed initial orthostatic hypotension during passive tilting, and we hypothesized that this condition was due to abnormal autonomic function. METHODS: The present study compared autonomic functioning in two groups of adolescents: patients with a diagnosis of initial orthostatic hypotension according to the tilt table test and patients with typical symptoms of initial orthostatic hypotension but normal tilt table test results. RESULTS: Significantly higher total composite autonomic severity scores and considerably higher adrenergic index were noted in the tilt table tested group. CONCLUSION: Initial orthostatic hypotension is possibly associated with autonomic dysfunction, especially abnormal vasoconstrictive ability, in individuals diagnosed with a tilt table test. Clinicians should take note of autonomic function when performing diagnoses of initial orthostatic hypotension using the tilt table test.
