title: [The method of the short term cardiorhytmogram analysis in estimation of estimation of fast change of human activity types].
abstract: A new high accuracy method of evaluation of individual RR-intervals distribution is described. The twofold benefits of quantiles measurement of short term RR-intervals distribution are high accuracy and reability of results as well as possibility to compare the results among different time spans. The method offered might be used to measure quick changes of human activity. The differences of individual RR-intervals distribution are revealed correlate to type and effectiveness of the activity during 60 sec periods.
