• According to the WHO Constitution, "Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity“ (1946).

• Health is primarily a state of the organism, which is characterized by the relation of structure and function, as well as the ability of regulatory systems to maintain a constant internal environment (homeostasis). (Nikolay N. Zajko, Prof., Dr. Med., Soviet pathophysiologist, 1908-1991).

• The disease is a disruption of the normal functioning of the body when exposed to damaging agents, resulting in a decrease of its adaptive capabilities (Nikolay N. Zajko).

• The disease is a dynamic state of an organism characterized by disruption of normal flow of life processes, resulting in reduced biological and social abilities of a person.

Prenosological approach

• Proposed by Soviet scientists Roman M. Baevsky, Vasily V. Parin and other (1966).

• Based on the analysis of subtle changes in the temporal organization of control actions of the nervous and endocrine systems on chronotropic function of the sinus node of the heart.

• Assumes a three-level hierarchical model of heart rhythm control.

Our body works according to the following rules:

• Normally, when the workload or everyday activity demands do not exceed the capacity of CVS (e.g. rest or light intensity work), the heart is regulated predominantly by autonomic level.

• When the workload becomes higher, the organism starts to involve baroreflex level of regulation.

• When the workload becomes too high or external conditions become too severe, the organism starts to involve sympathetic ergotropic and humoral level.

• So, the higher intensity of work or adaptation, the higher level of regulation is involved.

• Each higher level of regulation inhibits activity of lower levels.• The state of stress is characterized by increased heart rate (HR), increased

sympathetic tone of ANS, increased blood pressure.• State of relaxation is characterized by decrease of HR, increase of

parasympathetic tone (synonym – vagal tone) of ANS.
