In the current study, we investigated the relation between cognitive performance and heart rate variability in visuospatial working memory. We used a visuospatial working memory paradigm involving simultaneous encoding, maintenance, active manipulation and retrieval to simulate routine daily activities. Subjects performed the visuospatial working memory paradigm which had 3 memory loads and simultaneous ECG recording was acquired for measuring heart rate variability. Based on the performance in the visuospatial working memory task, subjects were segregated into two groups: Good performers and poor performers. Two major findings emerged in this study. First, the heart rate variability decreased with an increase in the working memory load. Second, good performers had relatively higher heart rate variability compared to poor performers while performing the visuospatial working memory task. Our results highlighted the influence of cognitive performance on heart rate variability. In summary, the current study indicates that the heart rate variability during the visuospatial working memory task could predict the qualitative differences in the cognitive performance between the individuals.

Resting Heart Rate Variability

Abstract. We hypothesized that in healthy subjects differences in resting heart rate variability (rHRV) would be associated with differences in emotional reactivity within the medial visceromotor network (MVN). We also probed whether this MVN-rHRV relationship was diminished in depression. Eleven healthy adults and nine depressed subjects performed the emotional counting stroop task in alternating blocks of emotion and neutral words during functional magnetic resonance imaging (fMRI). The correlation between rHRV outside the scanner and BOLD signal reactivity (absolute value of change between adjacent blocks in the BOLD signal) was examined in specific MVN regions. Significant negative correlations were observed between rHRV and average BOLD shift magnitude (BSM) in several MVN regions in healthy subjects but not depressed subjects. This preliminary report provides novel evidence relating emotional reactivity in MVN regions to rHRV. It also provides preliminary suggestive evidence that depression may involve reduced interaction between the MVN and cardiac vagal control.
