[The function of neuromuscular structures and the cerebrospinal dynamics in primary arterial hypotension]

To specify correlations between neuromuscular, vegetative functions and CSF dynamics in patients with primary arterial hypotension, 22 young patients were examined with the aid of stimulation electroneuromyography, registration of evoked sympathetic cutaneous potential, echoencephalography and electrothermometry. The data obtained before and after antiorthostatic test were compared. A group of healthy subjects served as control. It has been shown that in patients with primary arterial hypotension with compensated neurological microsymptomatology, unpronounced under common conditions, there are well-defined signs of disorders in the work of neuromuscular structures, vegetative fibers, and in thermoregulation. These disorders undergo different changes under the influence of the antiorthostatic test and are accompanied in the majority of the patients by the enlargement of the ventricular system of the brain. It is assumed that in view of this fact, potentialities of adaptation are decreased in the disease in question. It is recommended that electroneuromyography and echoencephalography be used in an all-round estimation of the health status of patients suffering from primary arterial hypotension.
