FIELD: medicine; electrocardiography.
SUBSTANCE: device can be used for measurement of duration of cardiac cycle, cycle segmentation, as well as in methods of analysis of variability of heart cycle. Device has filter which has to be input of device, analog switch, clock-pulse oscillator, two comparators, two threshold levels formers, four AND gates (output of third AND gate has to be output of device),two pulse counters, flip-flop. Second pulse counter counts number of adjacent readings which go out of threshold limits, and the second counter doesn't allow first counter to begin to count readings from scratch in case pulse error appears.
EFFECT: improved reliability of selection of beginning of cardiac cycle.
