COMPARISON OF VEGETATIVE REACTIONS USING FREQUENCY DOMAIN DATA REDUCTION

Abstract

There are many physiological models explaining the process of psycho-physiological adaptation and coping mechanisms in the man-environment interaction. Some of these adaptation models analyze the connection between the development of vegetative symptoms and environmental effects from the point of view of vegetative homeostasis. The process how the vegetative control becomes instable can be studied well in the early stages of illness, before the chronic disease develops. At this stage, the changes are reversible, in case of appropriate conditions, but the instable status may lead to the pathological stability as well. This chapter discusses the characteristics leading to the pathological stability in the early stages of two so called vegetative diseases—the hypertension and the ulcus duodeni—and presents the compare of these characteristics between these two groups and a control group.
