METHOD OF DETERMINING INDICES OF VARIABILITY OF OPERATOR'S HEART RATE IN REAL-TIME MODE AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC A61B5/402 A61B5/24 

FIELD: medicine.

SUBSTANCE: invention relates to medicine. In method realisation electrocardiosignal is filtered, discretised by time. Support points are singled out in q first cardiocycles, durations of cardiocycles, average duration of cardiocycles and number of discrete counts N, corresponding to this duration, average power P₀ of counts are determined and two threshold levels of power Δ₁=1.5P₀ and Δ₂=0.5P₀ are formed. At each step of discretisation total power of following each other N counts is determined, obtained value is compared with threshold levels Δ₁ and Δ₂. On each cardio cycle quantity of counts, corresponding to average duration of all cardio cycles is determined, quantity of taken in turn counts of total power, which exceed Δ₁, and do not exceed Δ₂ is calculated. Device contains filter, unit of discretisation, generator of timing pulses, unit of formation of support points, unit of determining value of average duration of cardiocycles, counter of cardiocycles, comparators, unit of squaring, units of determining average and total power of counts, formers of threshold levels, pulse counters, unit of calculating values variability indices.

EFFECT: invention makes it possible to increase reliability and authenticity of determining index of operator's heart rate variability.
