FIELD: medicine.
SUBSTANCE: method involves filtering electrocardiogram signal and digitizing it in time. Reference points are marked in the first q cardiocycles and durations of the cardiocycles are determined. Their mean duration and the number of discrete readings N corresponding to the mean duration, are determined. Cardiocycle duration variation threshold is set with the view on data received. Readings mean power P0 is also determined within the first q cardiocycles time interval, and two power threshold levels are formed: Δ1=1.5P0 and Δ2=0.5P0 and cardiocycle duration variation threshold values Nthr =kN, where k =0.25. Total power of N readings following each other is determined and the obtained value is compared to threshold levels Δ1 and Δ2 at each discretization step. The number of readings taken in turn and exceeding Δ1 and not exceeding Δ2 are counted. Threshold value Nthr being reached, arrhythmia occurrence signal is formed. Device has filter, digitizing unit, clock pulse oscillator, unit for forming reference points, unit for determining mean cardiocycle duration, cardiocycle counter, unit for forming cardiocycle duration variation threshold value, three comparators, squaring unit, unit for determining mean power of readings, unit for determining total power of readings, two power threshold level formers, OR-gate, pulse counter.
EFFECT: high reliability in determining available arrhythmia; high quality of cardiovascular disease diagnosis.
