[Mathematical model of the sinus rhythm of the heart]

As a result of mathematical simulation a group of signs was formed necessary and sufficient for the description of the oscillatory structure of the cardiac sinus rhythm at the quasi-stationary sections of the recording. The practical employment of the "adjustable" model permits one to obtain the present statistical accuracy of the assessment of signs with a lesser amount of baseline data. A procedure for the automatic measurement of signs by a mini-computer has been elaborated.
