[The evaluation of the adaptation of pupils starting instruction at 6 years old to new academic programs by using a computer analysis of cardiac variability].

Examination of the pulse variability of 6 years old (experimental group) and 7 years old control group schoolchildren is performed for establishing their adaptation capability to the educational process at the end of VI and VII class. 76 schoolchildren are comprised in the investigation. The analysis of the pulse variability is made on the basis of 10 min. ECG record on telemeter "Biomedica". A computer processing is made on the records by complex programmes for receiving indices related to the statistical characteristic of the dynamic order of cardiac intervals and to such giving their distribution. The receiving statistically significant differences for most of the indices between both groups of schoolchildren from VI class show an expressed activation of the adrenergic mechanisms with EG as well as higher "physiological value" of adaptation to the educational process. In VII the class the indices of the heart variability with EG practically show no differences from those of CG. This ascertainment proves, that at the age of 13 the potentialities for studies of those children starting school at 6 years are compensated with the children starting school at 7 years. This imposes the studies and the organization of the educative process for both 6 and 7 years old schoolchildren to be taken into consideration, to the completion of 7th class, with their age adaptive potentialities.
