Diagnosis of the Functional State of Autonomic Regulation and Prognosis of Maladaptation Development

Abstract

It was demonstrated that medical students with vagotonia and sympathicotonia had a mild strain of their regulation mechanisms. The considerable signs of autonomic regulation inefficiency were found out in conditions of physical exercising. The adaptation of individuals with vagotonia to the physical loading was going mainly due to the excessive elevation of heart rate along with the increase in diastolic blood pressure. In contrast, abnormal elevation of pulse pressure after physical loading was observed in young people with sympathicotonia, which is concerned as a negative prognosis and also a predictor of arterial hypertension. Some physiological aspects of the recovery period confirmed the insufficiency of autonomic regulation as well as discoordination of the reciprocal departments of autonomic nervous system in examined persons. The unfavorable range of increase in hemodynamic parameters after physical loading was to pioneer. The following ranges of cardiovascular indexes indicated the mild level of maladaptation: in individuals with vagotonia – Mean Arterial Pressure by 6-30%, heart rate by 80-120%, endurance coefficient – 5-27%, and Robinson’s index – 121–200%; in persons with sympathicotonia – endurance coefficient – 5-27%, and Pulse Pressure – 75-105%. These changes have to be corrected in advance for the prophylactics of specific and nonspecific complications of visceral systems functioning. The economical effectiveness of this research is accomplished by the reduction of financial expenses because of prophylactics and/or diagnosis of autonomic deregulation development
