Sažetak:
The aim of this study was to compare levels and patterns of heart rate variability during working night shift and the same period of non- working nights. Eight nurses from the Surgical Department of Zadar hospital, aged 25-33 years, participated in this study. The study included continuous recordings of cardiac activity during 10 hours of night-shift working (09.00 pm - 07.00 am) and during the equivalent non- working night period. As expected, the analyses showed differences in the levels of cardiac activity between working and non-working nights. Non-working nights were characterised by longer R-R intervals, higher variability indices and a greater parasympathetic effects on cardiac activity, while their patterns of changes and spectral compositions were rather similar to those obtained during working nights. Obtained results showed the supremacy of the circadian pattern of changes, i.e. parasympathetic prevalence, during both, working and non-working nights. Parasympathetic prevalence during night shift working seemed inappropriate, since normal working implies sympathetic activity. This is particularly true for the periods between 04.00 and 06.00 am, when various parameters indicated almost the same level of arousal during working and non- working night. Certainly, the lack of sympathetic activity and parasympathetic dominance during working night represents a discrepancy between the work requirements and the momentary capabilities of the organism to meet them. Due to this, it represents a major source of stress in night-shift working.
