“…[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.

“…Indeed, some research has reported findings of lower HRV in African Americans relative to Whites (e.g., Choi et al, 2006; Lampert et al, 2005), whereas other research has shown higher HRV in African Americans (Liao et al, 1995; Wang et al, 2005). More recently, Hill and colleagues (2015) conducted a meta-analysis of 17 studies comprising more than 11,000 total participants, reporting ethnic differences in basal HRV between African Americans and Whites.…”

Objective Previous research attempting to delineate the role of discrimination in racial/ethnic disparities in hypertension has focused largely on blood pressure, which is chiefly governed by the sympathetic branch of the autonomic nervous system. Consequently, few studies have considered the role of the parasympathetic branch and particularly its regulation of the heart via the vagus nerve. Method In the present cross-sectional study, we employed hierarchical linear regressions to examine associations between perceived ethnic discrimination and resting heart rate variability (HRV), an important biomarker of parasympathetic cardiac modulation and overall health, in a sample (N = 103) of young, healthy African American participants (58% female, Mage = 19.94 years, SD = 2.84). Results After accounting for demographic factors and health status characteristics, lifetime discrimination emerged as an inverse predictor of HRV. When subdomains of discrimination were considered, discrimination attributable to threats or actual acts of aggression was also predictive of lower HRV. Conclusions Our findings suggest that a greater lifetime burden of discrimination and discriminatory harassment and/or assault is associated with lower resting HRV in African Americans. The implications of these findings are discussed in the context of past, present and emerging research emphasizing biological linkages between discrimination and health.

“…Factors including age, body mass index, alcohol consumption, cigarette smoking, and even ethnicity can affect autonomic function. Mentioned factors lead to different HRV in both groups (Choi et al, 2006;Elsenbruch, Harnish, & Orr, 1999;Hogarth, Graham, Mary David, & Greenwood, 2009;Kuo et al, 1999;Moodithaya & Avadhany, 2012;Palisso et al, 1999;Regitz-Zagrosek, Lehmkuhl, & Weickert, 2006;Tanaka, Kimura, Goyagi, & Nishikawa, 2004;Uusitalo et al, 2007). In the current research, the focus was on possible effects of gender on HRV and autonomic dysfunction in epileptic patients.…”

Gender-Related Differences in Heart Rate Variability of Epileptic Patients

Recently, heart rate variability (HRV) analysis has been used as an indicator of epileptic seizures. As women have a lower sudden, unexpected death in epilepsy risk and greater longevity than men, the authors postulated that there are significant gender-related differences in heart rate dynamics of epileptic patients. The authors analyzed HRV during 5-minute segments of continuous electrocardiogram recording of age-matched populations. The middle-aged epileptic patients included males (n = 12) and females (n = 12), ranging from 41 to 65 years of age. Relatively high-(0.15 Hz-0.40 Hz) and low-frequency (0.01 Hz-0.15 Hz) components of HRV were computed using spectral analysis. Poincaré parameters of each heart rate time series were considered as nonlinear features. The mean heart rate markedly differed between gender groups including both right-and left-sided seizures. High-frequency heart rate power and the low-frequency/high-frequency ratio increased in the pre-ictal phase of both male and female groups (p < .01), but men showed more increase especially in right-sided seizures. The standard deviation ratio, SD2/SD1, of pre-ictal phase was greater in males than females (p < .01). High-frequency spectral power and parasympathetic activity were higher in the female group with both right-and left-sided seizures. Men showed a sudden increase in sympathetic activity in the preictal phase, which might increase the risk of cardiovascular disease in comparison to women. These complementary findings indicate the need to account for gender, as well as localization in HRV analysis.

Age and Ethnicity Differences in Short-Term Heart-Rate Variability

Abstract: Young African Americans manifested a pattern of HRV response similarly to older Caucasian Americans. These results suggest that young African American individuals might show signs of premature aging in their autonomic nervous system.
