[Basis for the discreteness of delay and frequency in diagnostic cardiostimulation]

The article presents the metrological, electrophysiological and economic aspects of the substantiation of the choice of the optimal discreteness of impulses and their frequency in diagnostic programmed cardiostimulation. It has been shown that in conducting the intracardiac electrophysiological examination the traditional choice of the discreteness of the interval delta T3 = 10 msec, and the discreteness of the frequency delta Fc = 10 impulses/min does not meet the metrological requirements. From the metrological viewpoint, the minimal values of the discreteness constitute delta T3 = 20 msec and delta Fc = 20 impulses/min, which are compatible with obtaining diagnostic information and thus justified from the clinical and expedient from the economic point of view.
