Background Heart rate variability (HRV) has been used as a measure of stress and mental
strain in surgeons. Low HRV has been associated with death and increased risk of cardiac …

Objective To determine the specific effects of working long hours in surgery and potential
cardiac stress in the individual surgeon by measuring heart rate variability (HRV). Design …

Purpose Adverse effects by night-call duty have become an important occupational health
issue. The aim of this study was to investigate whether the heart rate variability (HRV) …

Background Resting heart rate is well established as a predictor of morbidity and mortality in
the general population. However, the relationship between preoperative heart rate and …

Emergency physicians (EPs) are a population at risk of chronic stress and work-related
exhaustion because their job is a complex interplay between stress (unpredictability of …

BACKGROUND: In residency programs, it is well known that autonomic regulation is
influenced by night duty due to workload stress and sleep deprivation. A less investigated …

Heart rate variability (HRV) refers to the variations between consecutive heartbeats, which
depend on the continuous modulation of the sympathetic and parasympathetic branches of …

Objective In a difficult and demanding environment such as the operating room, the
individual workload response of physicians is of particular importance. The aim of this study …

Measurement of heart rate variability (HRV) is useful in assessing the function of the
autonomic nervous system and in staging of clinical diseases. The purpose of this study is to …

Heart rate variability (HRV) is a predictor of mortality and morbidity after non-lethal cardiac
ischemia, but the relation between preoperatively measured HRV and intra-and …
