Background: There is evidence for an increased cardiovascular risk of shift work from epidemiologic and field studies. The aim of the present study was to assess the health risk by studying cardiovascular autonomic control and screening of supraventricular and ventricular extrasystoles (SVE/VE), and to determine whether a functional association exists between cognitive work-related factors and cardiovascular autonomic control in shift workers. Methods: Heart Rate Variability (HRV), SVE/VE were assessed based on 10 minutes Electrocardiogram recordings, workrelated factors were measured by NIOSH Job Stress Questionnaire in 99 telephone operators. Results: The comparison of the mean values of HRV indices between operators on non-shift and shift schedules did not show significant changes in the autonomic cardiovascular control. No significant changes were found in myocardial activity. The study of the relationship between autonomic cardiovascular control, and work-related factors revealed significant dependence of mean heart rate on skill utilization and significant dependence of Short-Term Variability on cognitive skills and skill utilization. Conclusions: The results of our study did not reveal a pattern of an increased cardiovascular risk in shift working telephone operators. Functional dependencies revealed that skill utilization and cognitive skills might exert a stress generating effect and affect the parasympathetic cardiac function.
