“…Use of microprocessors provides automation of processing of the cardiointerval distribution function and analysis of VNS conditions [2,3]. The device for automatic recording of electrocardiographic signals previously developed in our laboratory [4] on the basis of the domestic microcomputer Elektronika MK-85M has such advantages as portability, possibility of upgrading the program of statistical analysis of the cardiac rhythm, light weight, high reliability, and low cost. Use of a PC decreases the expense of development of cardiointervalometric analyzers.…”
