METHOD OF HUMAN STRESS DIAGNOSTICS Russian patent published in 2017 - IPC A61B5/02 

FIELD: medicine.

SUBSTANCE: patient is recorded cardiothrit during 12 hours of daytime during his daily activity. Then, once every half an hour, a 5-minute recording interval without interference is analyzed, the standard deviation of the NN intervals (SDNN) of each of the indicated 5-minute intervals of the cardiorhythmogram is calculated. Determine by the average SDNN of 5 minute intervals the average SDNN value for every third part of the 12-hour daytime period of the day. Diagnosing chronic stress in obtaining mean SDNN values for the second and third parts of daytime, each of which differs from the mean of the preceding third of daytime of the day by less than 10 milliseconds and/or the average SDNN value for the first third of the daytime, which is less than 70 milliseconds, with an average SDNN value for the subsequent second third of daytime, equal to or less than the SDNN value for the first third of the daytime.

EFFECT: method allows to provide the possibility of diagnosing chronic stress with high informativeness and reliability.
