We aimed to investigate the possible harmful effects of sleep deprivation on cardiac rhythm, specifically heart rate variability (HRV), in work shift physicians. Patients and Methods: Eighty seven healthy male physicians participated in this study. The present study was done in Ankara, Turkey, from January to September 2014. Work shift (sleep deprivation) group (n=45) remained awake for 26 h. Non-work shift group slept in their homes. ECG (HRV) was applied at 9 am for both shift and non-shift groups. Results: Almost all HRV parameters, except LF/HF, decreased in the work shift group compared with the non-shift group. Conclusions: Sleep deprivation due to work shift may cause sympathovagal imbalances by affecting the biological rhythm.eninfo:eu-repo/semantics/closedAccessWork; RiskArticle384E233E2362-s2.0-84939176631Q2WOS:000359119100017Q4
