[The diagnostic significance of evoked cutaneous sympathetic potentials].

A study was made of evoked cutaneous sympathetic potentials in healthy persons, in simulation of emotional stress, in physical and orthostatic loads as well as during administration of 40 mg anapriline, 120 mg gangleron, and 15 mg diazepam. The purpose of the study was to identify factors that influence evoked cutaneous sympathetic potentials (ECSP). The mechanisms are reviewed of cutaneogalvanic reaction underlying ECSP. The data obtained were compared to those in patients with diabetes mellitus, Charcot-Marie amyotrophy, Guillain-Barré syndrome, Raynaud's disease, essential hyperhidrosis, panic attacks, and spinal amyotrophy. Analysis of ECSP makes it possible to reveal both brain function and primarily the presence of pathological alterations in the peripheral (segmental) autonomic nervous system.
