rhythm registration at use of acoustic influences

81 experiment is spent to 5th series with participation in quality of examinees practically healthy, physically not trained 8 men and 6 women at whom registration RS was twice spent trehetpnaja. In 1 th part of experiences (control) examinees in position sitting listened to the rhythm of own heart transformed to sound signals pulsotahometra, for experimentally established time equal of 13 mines (10 mines - influence, 3 mines - the season after influence).

In 2nd part examinees listened sounded pulsotahometrom own RS in an initial state (1st stage). At 2nd stage scoring of own rhythm stopped, and experiment joined rhythmical influence by the computer metronome which has been adjusted on frequency of warm reductions (CHSS) of the examinee, lowered for 10 ud/minute Thus the examinee was offered to listen attentively to a replicated rhythm, mentally identifying it with own RS. At 3rd stage frequency of a metronome has been lowered on 20 ud/mines, on 4th - for 30 ud/minutes Then, after 3-minute rest during which the examinee heard own sphygmus, again
Two-minute registration of a warm rhythm (5th stage) was carried out. 3rd part differed from 2nd themes, that the metronome was adjusted on CHSS, raised on 10 (2nd stage), 20 (3rd) and 30 (4th) impacts.

According to the above-stated 5 series on R.M.Baevskomu, in a kind kardiointervalogramm (KIG) parametres RS automatically paid off with calculation of mathematical expectation DSTS (an average error (m), a standard deflection (S) and dispersions (D), fashions (Mo) and voltages of a fashion (amo), quotient of variability DSTS (Sl) and a strain index (IN). Statistical analysis RS provided construction intervalogramm and allocation polygons kardiointervalov. For an establishment of intrinsic communication of studied processes definition of autocorrelation function with correlation coefficient analysis on the first alteration of a file (r1) and construction of the conforming schedules was spent. At the description of a randomness of rhythmic processes RS the program of calculation built in the computer normirovannogo scope on method Harsta characterising fraktalnuju dimension was used.

Spectral analysis RS included calculation of following parametres of a frequency spectrum: spectral vigour for all season of registration according to the general frequency (OCH) a spectrum, vigour in a range of very low frequencies (ONCH, low frequencies (LF), high frequencies (VCH) ritmogrammy, and also the LF attitude to VCH (NCH/VCH). The given parametres are selected by us as most full characterising levels of regulation RS and their mutual relations.
