[Typological features of cardiac regulation and emotional stress in man when achieving his results under test loads].
The relationship between heart rate and errors and work quality was studied in the examinees during somatosensory, mathematic, and Lindolt's tests. There was a significantly higher correlation between the time course variations of heart rate, the types of cardiac regulation (central, respiratory, autonomic), and the levels of the achieved. There was a basic difference between the groups of subjects in their responses to testing errors, by reflecting in altered heart rate and work quality.
