title: [Functional state of the autonomic nervous system according to the data of heart activity during performance of a computerized visual-spatial task].
abstract: The influence of the performance of a computerized visio-spatial task on the state of the autonomic nervous system of PC operators was studied. Statistical characteristics of the operator's heart rhythm during the 3-hour period of work on a computer were analyzed using Baevsky's method of variational pulsometry. The operators were classified in three groups by the character of their reaction to loading. It was suggested that the visio-spatial task performance on a computer could act as a stress factor only on a certain category of people.
