“…Similar observations were e also reported. 10,11 Again, among the other time domain parameters, SDNN have been failed to show any age effect whereas RMSSD were found consistently and significantly decreased in middle age and older people and also showed significant correlation with age in older subjects specially. No published data are available to compare these findings.…”

“…[10][11][12][13][14][15][16][17][18][19] Different time domain components of HRV has been used as marker of overall cardiac autonomic activity. The task force guideline for HRV analysis have demonstrated the interpretation of these parameters to understand the status, behavior and the balance between sympathetic and parasympathetic function due to their continuous interaction.…”

Background: Heart rate variability has been considered as an indicator of autonomic nerve function status. Few works have been done to assess the heart rate variability in normal healthy subjects in different countries. Objectives: To assess the cardiac autonomic nerve function status in healthy Bangladeshi population of different age groups by analyzing time domain measures of Heart Rate Variability. Methods: This cross sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka from the period of July 2012 to June 2013. For this purpose, a total number of 180 healthy subjects were selected with the age ranging from 15-60 years of both sexes. All the study subjects were divided into 3 different groups according to age (Control 15-30 years; middle age 31-45 years; older age 46-60 years). Each group included 60 subjects of which 30 were male and 30 were female. The subjects were selected from different areas of Dhaka city by personal contacts. HRV parameters were recorded by a 4 active channels, RMS Polyrite-D-2 machine For statistical analysis, one way ANOVA, unpaired Student's 't'-test and Pearson's correlation coefficient test were performed. as applicable. Results: Systolic blood pressure (SBP), diastolic blood pressure (DBP) were significantly (p<0.001) higher in older group in comparison to control & middle age group. Again RR interval and RMSSD (p<0.001), were significantly lower in older age group (p<0.05) compared to control & also to middle age group. But HR was found significantly higher (p<0.05)in both middle and older subjects than control and also in older (p<0.05) compared to middle age. Correlation analysis showed moderate negative correlation of mean R-R with age in middle age whereas significant negative correlation for RMSSD both in middle and older age subjects.. Conclusion: In this study, markedly decreased cardiac parasympathetic function were found with aging process.

“…Female gender seems to result in a lower total variability (Vandeput et al 2012), whereas vagal modulation has been found to be similar (Moodithaya & Avadhany, 2012) or higher (Fukusaki et al 2000;Huikuri et al 1996) when compared to men. These differences in HRV are probably caused by lower sympathetic and higher vagal control of the heart in women (Carter et al 2003).…”

“…HRV is known to decline with age (Byrne et al 1996;Fukusaki et al 2000;Moodithaya & Avadhany, 2012). It has been concluded that age-related changes in HFP, reflecting vagal modulation, are primarily mediated by aging per se and not by physiological changes like physical fitness, body composition or blood pressure, which are characteristics of normal aging (Byrne et al 1996;Fukusaki et al 2000).…”

“…Scientific literature do support the difference in autonomic reactivity among gender but not free from conflicting observations. [5,6] Autonomic tone refers to the resting basal discharge or basal activity free from physiological perturbations or challenges. [7] This is in sharp contrast to autonomic reactivity which measures the degree of change or activity of a system in response to a given stimulus.…”

Background: Initiated by biological plausibility and supported by the pilot study, we observed possibility of associations between cardiovascular autonomic milieu and academic performances. As there are established cognitive ability differences among gender in literature, we designed a study to observe the differences in the basal autonomic activity as well as the manner of association between autonomic activity and academic performance between genders. Considerable lacunae in literature on this aspect also warranted for scientific introspection on this lacuna. Aims and Objective: The aim of this study is to observe the association between resting short-term heart rate variability (HRV) indices and University marks of anatomy, biochemistry, and physiology in young male and female medical students. Materials and Methods: Cross-sectional observational study with 102 healthy young participants in which 34 boys and 68 girls between 18 and 22 years were included by convenient sampling after assessing the inclusion and exclusion criteria. HRV is computed under standard conditions as per the task force recommendations in time and frequency domains. The academic performance is assessed by University examination marks at the end of the 1 st year. The comparison of HRV parameters, academic performance, and their associations was analyzed separately by gender. Type 1 error allowance fixed at 5% but considering the high dispersion of HRV data, P values between 0.1 and 0.05 were also discussed. Results: Mean RR intervals showed a negative correlation with academic performance in males. Time domain and geometric indices of HRV showed a negative correlation in boys but not in girls. In case of frequency domain indices, all indices of sympathetic activity showed a positive correlation with academic performance in boys and not in girls. Furthermore, sympathetic indices are more in males compared to females. All indices of parasympathetic reactivity were negatively correlated with academic performance in males. Conclusion: High-sympathetic activity is correlated with better cognitive ability in males but the same association is not seen in females.
