9. Regulation in the disease
Probabilistic nature of diagnostic findings
Medicine, clinical diagnosis, above all, is probabilistic in nature.
HRV technology provides a quantitative assessment of the status of regulatory systems.
In medical practice, however, it is customary to operate with fuzzy sets.
In assessing the patient’s state of health, in our case of regulation, it is natural to use such terms as, little, moderately, strongly, excessively, etc.
Regulation, like other functions, is subject to short- and long-term
The found parameters of HRV estimate it at the time of the study with a combination of limiting conditions.
That is why quantitative results in their interpretations and subsequent use should describe in terms of fuzzy sets.
