Key result
Higher parasympathetic HRV links to better executive neurocognitive performance, with task-dependent variation.
Why the study?
Heart rate variability has the potential to predict cognitive performance, leading researchers to explore differences in neurocognitive performance between workers with high versus low HRV.
Does high heart rate variability correlate with improved neurocognitive performance in healthy white-collar and blue-collar workers?

Does high heart rate variability correlate with improved neurocognitive performance in healthy white-collar and blue-collar workers?
Cardiac vagal control serves as an indicator of neurocognitive functioning, highlighting the importance of assessing task-dependent HRV parameters in different workforce populations.

Higher HRV may mark better executive function in workers; hypothesis-generating and should not yet change occupational screening.
Heart rate variability (HRV) has the potential to be a predicting factor of cognitive performance. The present research aimed to explore the differences in neurocognitive performance of workers with high HRV and low HRV. A total of 48 white-collar workers and 53 blue-collar workers were assessed. An electrocardiogram was used to obtain HRV data, whereby a 10 min baseline and an active (neuropsychological task) recording were taken. Median splits were performed on data to obtain high- and low-HRV groups. The Cambridge Neuropsychological Test Automated Battery, specifically, the spatial working memory, attention-switching task, rapid visual processing, and spatial span were used. Higher HRV (RMSSD and HF) was linked to better neurocognitive performance measures. Interestingly, the blue- and white-collar groups exhibited different correlations and, in some cases, showed an inverse relationship with the same variables. The differences observed in the present study demonstrate the importance of assessing task-dependent HRV parameters.

Eslami et al. (2023) reported a cross-sectional. High Heart Rate Variability (HRV) vs. Low Heart Rate Variability (HRV) was evaluated on Neurocognitive performance measured by the Cambridge Neuropsychological Test Automated Battery (CANTAB) including spatial working memory, attention-switching, rapid visual processing, and spatial span. Higher parasympathetic heart rate variability (RMSSD and HF) was generally associated with better neurocognitive performance in executive tasks, though specific responses were task-dependent and varied by occupational group.
