Heart Rate Variability during Performance of Various Resultive Tasks

Heart rate variability was studied in 30 subjects before and after the assembling of a single-type color mosaic. The heart rate analysis was performed by evaluating its statistical structure (variation curves, scatter plots, and standard deviation). The wave structure of a series of cardiointervals was assessed by calculating and plotting the autocorrelation function. Certain heart rate parameters in different subjects reflected to various extents their success in achieving the useful end result of the visuomotor design task.
