摘要：	Psychophysiological and occupational research has considered the dependence of stress and lowered work satisfaction on work demands as basic. In this study, the authors observed a functional relationship between cognitive workload assessed by heart rate variability (HRV) and heart rate (HR), and work stress measured with work-related psychosocial factors. The result is consistent with the result of Hockey et al., who reported a functional association between workload and work stress. The country of Bulgaria is in a transition period, and work activity is associated with difficulties in adaptation to new technologies, the necessity of acquiring new skills and knowledge, and working with new technologies, etc. The prolonged effect of work-related factors could induce an abnormal pattern of regulatory activity and could affect cardiovascular regulatory mechanisms: parasympathetic function - P(sub RSA), and baroreceptor modulation of heart rate - P(sub THM). The functional dependence of cognitive demands and work satisfaction on vagal activity assessed by P(sub RSA) could promote future research on the association between cognitive workload, work stress, and performance in considering the role of P(sub RSA) as an indirect measure of performance and as a direct indicator of the cardiovascular protective function. Four groups of operators and one referent group participated in the study: 99 telecommunications operators working with information technology systems, 96 military pilots from the Bulgarian Military Air Force, 61 computer operators from the petroleum construction and assembly industry, 57 air traffic controllers for Bulgarian civil air traffic, and 42 clerks who did not work with automated systems. The results of these field studies clearly indicate that operators are exposed to the effects of cognitive load and work stress factors that are a function of their interaction with an automated system.
