The Effect Of Mental Stress On Heart Rate Variability And Blood Pressure During Computer Work, Euro. J. Appl. Physio.
The aim was to evaluate the cardiovascular and subjective stress response to a combined physical and mental workload, and the effect of rest. (...) Beat-to-beat blood pressure and electrocardiogram (ECG) were recorded continuously during the experiment. The participants reported subjective experiences of stress (...) before and at the end of the work. Heart rate variability (HRV) variables were calculated from the ECG recordings, and a reduction in the high-frequency component of HRV and an increase in the low- to high-frequency ratio were observed in the stress situation compared to the control session. No changes were seen in the low-frequency component of HRV. (...)
