title: [Some regularities of the pulse rate variability].
abstract: Histograms of heat rate for 878 persons of both sexes aged from 3 to 83 years have been analyzed. The total data sampling was more than one hundred thousand pulse beats. Summary bar charts (variance pulsograms) were built up separately for men and women. Within the range of 60-75 beat/min, the peaks with the beat rates corresponding to 60, 61, 63, 65, 68, and 75 beat/min were observed, their values being twice as big as those of the neighbouring ones. Within the range of 79-99 beat/min, minima were observed with beat rates of 79, 87, 91, 94, 97, and 99 beat/min. The distribution of these beat rates can be approximately described by the members of Fibonacci series from the determining beat rate of about 59-60 beat/min (maximuma) and about 101/102 beat/min towards a decrease in the beat rate (minima). The determining beat rates of about 60, 101, and 162 beat/min may be evidence of the hierarchy, which is also approximately described by the array close to the Fibonacci series. Within the range of 101 to 115 beat/min, the peaks for men are marked that correspond to the harmonic series with a period of 2 beat/min, i.e., 101, 103, 115 beat/min.
