Heart rhythm variability characteristics were studied in volunteers with different stability of the results upon switching from one type of intellectual activity to another. Individuals with stable results differed from those with worse accuracy of information reproduction by high initial CV, total power of heart rhythm variability and power of VLF, LF, and HF spectra. Volunteers with stable results were characterized by high lability manifesting by changing values and proportions of heart rhythm variability characteristics at different stages of activity and by the absence of a relationship between these parameters at different stages of activity and initial status of the volunteer. VLF spectrum power decreased with impairing the accuracy of information reproduction.
