“…The lowest TINN values were found during the morning. The highest LF and LF/HF values were during the morning, as predicted by other studies [19,20,32]. The highest HF values were during the night, which is consistent with previous studies [20,33].…”

In this study perceived mental stress during occupational work was compared to heart rate variability (HRV) using a traditional questionnaire and a novel wristop heart rate monitor with related software. (r = -.73 and r = -.60, respectively). The analysis shows that as the RMSSD and TINN value differences increase from night to morning, the stress decreases. The aim was to find HRV parameters useful for mental stress detection. We found the highest correlation between perceived mental stress with the differences between the values of triangular interpolation of rythm-to-rythm (RR) interval histogram (TINN) and the root mean square of differences of successive RR intervals (RMSSD) obtained in the morning and during the workdaywork stress wristop computer heart rate variability o o 276

“…Data recordings were carried out in an air-conditioned quiet laboratory at an ambient temperature of 25 ± 2°C and humidity of 50 ± 5% between 10:00 and 17:00 on one day, to minimize the effect of the circadian rhythm on the ANS (Bilan et al 2005). All 29 women were monitored once in the early follicular phase, defined as the first or second day after the menstrual phase based on the self-reported menstrual cycle, to avoid the influence of sex hormone levels on HRV (Tenan et al 2014).…”

Some studies have reported that recumbent position may have advantages in patients with heart disease and in pregnancy. However, it remains controversial whether recumbent position affects autonomic nervous system activity and hemodynamics in healthy adults. The aim of this study was to evaluate alterations in heart rate variability (HRV) and hemodynamics in the supine, left recumbent and right recumbent positions in healthy young adults. A total of 80 participants aged 22.8 ± 3.1 years were enrolled in this observational study. Fifty-eight volunteers (29 men and 29 women) maintained the supine position followed by the left and right recumbent positions, while electrocardiographic data were recorded for spectral analysis of HRV to assess cardiac vagal nerve and sympathetic nerve activities. The heart rate (HR) was significantly lower in the left recumbent position than in the other positions. There were no statistically significant differences in HRV among the three positions. Considering the possibility that the echographic procedure affects autonomic nervous system (ANS) activity, the other 22 participants (11 men and 11 women) underwent an echographic evaluation of hemodynamics in the heart and inferior vena cava (IVC) across the three positions. Although a low HR was also observed, there were no statistically significant differences in the IVC or the heart blood volume between the supine and the left recumbent positions. A postural change to the left recumbent position does not affect the cardiac blood circulation or ANS activity, though it does decrease HR in healthy young adults. This finding indicates that the lower HR in the left recumbent position is not attributable to the ANS activity.

“…Short-term HRV, usually derived over 5 minute ECG segments, is suitable for laboratory experiments, and can be analysed under rest conditions or in response to different sympathetic or parasympathetic manoeuvres. Long-term 24-hour recordings may provide useful information about circadian rhythms (Bilan et al 2005) and autonomic balance during sleep (Hallman and Lyskov 2010).…”
