Abstract: A method and apparatus for correction of a functional state of a subject organism is provided. In one embodiment, the method includes: a) measuring one or more biosignals reflecting a current functional state of the subject organism, b) transforming and processing the one or more measured biosignals to provide a current generalized index of health of the subject organism, c) evaluating a deviation of the current generalized index of health from a predetermined predicted optimal generalized index of health, d) forming of external effect on the subject organism using a controllable factor of effect having one or more controllable parameters, and e) regularly repeating the external effect until the deviation of the current generalized index of health from the predicted optimal generalized index of health is minimized and stabilized. The subject organism may be a patient. The patient may be a person.

Abstract: A method and apparatus for integral evaluation of a state of a regulation system of a subject organism is provided. In one embodiment, the method includes: a) registering a heart interval RR, b) measuring a succession of heart intervals RR to determine an integral approximation of a heart rate variability, c) performing a spectral decomposition on the succession of heart intervals RR to develop a spectrogram, d) fragmenting the spectrogram into low frequency, medium frequency, and high frequency ranges, and e) determining a first state of the regulation system by determining an index based at least in part on a capacity of the designated frequency ranges for the subject organism and corresponding predetermined average capacities of the designated frequency ranges for a like organism. In one embodiment, the apparatus includes: a plurality of sensors and a signal processing block. In another embodiment, the apparatus also includes a visualization device.
