Abstract Background Resting heart rate (HR) and its variability (HRV) reflect cardiac sympathovagal balance that can stimulated by head-up tilting. HRV is significantly influenced by the level of HR, but how much HRV offers additional information about cardiac autonomic tone than HR alone remains unresolved. We examined the relation of resting HR with short term HRV during passive head-up tilt.Methods Hemodynamics of 569 subjects without medications with direct cardiovascular effects and known cardiovascular diseases were recorded using whole-body impedance cardiography, continuous radial pulse wave analysis and electrocardiography based HRV analysis in supine and upright positions. For statistical analyses the study population was divided into tertiles of resting heart rate according to sexes.Results Higher low frequency to high frequency ratio (LF/HF) of HRV (reflecting sympathovagal balance) was associated with higher HR in supine (p<0.001) and upright positions (p=0.008). The outcome was similar when the HRV analysis was based on HR instead of RR-intervals (p<0.001 supine, p=0.012 upright). The lowest HR tertile presented with higher supine to upright increase in LF/HF than the highest HR tertile (1.1 vs. 0.85, respectively, p=0.037).Conclusion Higher resting HR is related to higher LF/HF in supine and upright positions, reflecting higher cardiac sympathovagal balance. Lower resting HR is associated with lower resting LF/HF, but with a more pronounced increase in both HR and LF/HF during head-up tilt, suggesting greater change cardiac sympathovagal balance in response to upright posture.

AbstractTo track blood pressure (BP) and resting heart rate (RHR) in children and adolescents is important due to its associations with cardiovascular outcomes in the adulthood. Therefore, the aim of this study was to examine BP and RHR over a decade among children and adolescents living in Germany using national examination data. Cross-sectional data from 3- to 17-year-old national survey participants (KiGGS 2003–06, n = 14,701; KiGGS 2014–17, n = 3509) including standardized oscillometric BP and RHR were used for age- and sex-standardized analysis. Measurement protocols were identical with the exception of the cuff selection rule, which was accounted for in the analyses. Different BP and RHR trends were observed according to age-groups. In 3- to 6-year-olds adjusted mean SBP and DBP were significantly higher in 2014–2017 compared to 2003–2006 (+2.4 and +1.9 mm Hg, respectively), while RHR was statistically significantly lower by −3.8 bpm. No significant changes in BP or in RHR were observed in 7- to 10-year-olds over time. In 11- to 13-year-olds as well as in 14- to 17-year-olds lower BP has been observed (SBP −2.4 and −3.2 mm Hg, respectively, and DBP −1.8 and −1.7 mm Hg), while RHR was significantly higher (+2.7 and +3.7 bpm). BP trends did not parallel RHR trends. The downward BP trend in adolescents seemed to follow decreasing adult BP trends in middle and high-income countries. The increase in BP in younger children needs confirmation from other studies as well as further investigation. In school-aged children and adolescents, the increased RHR trend may indicate decreased physical fitness.

ObjectivesThe purpose of this study was to determine orthopaedic surgery residents’ and attending surgeons’ resting heart rate (RHR) and heart rate variability (HRV) and if there is a correlation between subject-specific variables (age, attending surgeon, resident, postgraduate year (PGY) level, gender, number of calls, total hours worked, and total hours of sleep) and surgeon RHR and HRV.MethodsOrthopaedic surgery residents and attending surgeons at a single institution were prospectively enrolled and provided a validated wearable device to determine hours of sleep, RHR and HRV. Demographic information, hours worked and overnight calls were recorded. Bivariate correlations were determined using the Spearman rank correlation. Multiple linear regression models were constructed to determine the effect of relevant variables. All p values were reported, and a significance level of α=0.05 was used (p<0.05).ResultsTwenty-one of 26 enrolled subjects completed the 4-week study. The average RHR and HRV for orthopaedic surgeons was 61.8+10.0 bpm and 42.96+21.2ms, respectively. Residents had a significantly higher RHR (66.4+8.4 vs 55.6+8.9, p=0.011) compared with attending surgeons. Overnight calls had the strongest association with decreased HRV (r=−0.447; p=0.038), moderate positive correlation with RHR (r=0.593; p=0.005) and weak negative correlation with HRV (r=−0.469; p=0.032). There was no significant correlation between PGY level, gender, total hours worked and total hours of sleep with RHR or HRV.ConclusionOrthopaedic surgeons have poor RHR and HRV. Additionally, the number of overnight calls had the strongest correlation with worse RHR and HRV.Level of evidenceLevel II; diagnostic, individual cross-sectional study with a consistently applied reference standard.

Background: This study aimed to compare and correlate the resting heart rate, body composition and heart rate variability among judo and wushu players. Method: 40 athletes (20 judo and 20 wushu players) were included in the study. Body composition (BMI, subcutaneous body mass, skeletal body mass, body fat %, body density, Visceral fat, Lean body mass) was evaluated with the help of 7 skinfold thickness and body circumferences with the help of Harpenden calliper and measuring tape respectively. HRV (RMSSD, SDNN, LF/HF, LFnu and HFnu) was recorded in resting state (~5min) with the help of Heart wear shimmer ECG device. Result: No significant difference of body composition and HRV variables (p> 0.05) was found between the two groups except Body fat % and body density (p<0.05) which differ significantly among the two groups. In Judo, LF/HF and LFnu showed significant positive correlation with BMI (p<0.05, r=-0.488), subcutaneous whole-body mass (p<0.05, r=-0.464), visceral fat (p<0.05, r =-0.508), and body fat % (p<0.05, r =-0.626. Whereas HFnu showed significant negative correlation with BMI (p<0.05, r=-0.488), subcutaneous whole-body mass (p<0.05, r=-0.464), visceral fat (p<0.05, r=-0.505) and body fat % (p<0.05, r=-0.626). Whereas no correlation was found between HRV and Body composition in wushu players. Conclusion: Reduction in body fat % and visceral fat in judo players indicate improved sympathovagal balance which can be due to the adaptation induced by training loads. Similar results were not seen in wushu players because of high amount of body fat% and visceral fat.

Neural control of the cardiac responses to exercise in air (running) and under water (diving) was studied in the muskrat (Ondatra zibethicus) by means of acute pharmacological blockade with the muscarinic blocker atropine and the beta-adrenergic blocker nadolol. Saline injection was used as a control. Controls running on a treadmill showed a marked increase in heart rate with exercise. Atropine-treated animals had a higher resting heart rate than controls, but heart rate still increased with running. Nadolol-treated animals had a lower resting heart rate than controls and displayed a less pronounced increase in heart rate with running than controls. Animals treated with a combination of atropine and nadolol had a resting heart rate similar to that of controls but their heart rate was unaffected by running. Thus, exercise tachycardia in muskrats is due to activation of the sympathetic system and also to a reduction in parasympathetic tone. Heart rate decreased markedly during voluntary submergence in controls but rose as muskrats swam submerged against increasing water flows. Nevertheless, diving bradycardia was still present. Free-diving bradycardia and the relative increase in heart rate with underwater exercise were abolished by atropine and unaffected by nadolol. Hence, unlike the cardiac response to exercise in air, the cardiac response to underwater exercise is due only to a reduction in parasympathetic tone. Injection of the beta-adrenergic agonist isoproterenol markedly increased heart rate in air but had little effect during voluntary and forced dives, indicating a marked decrease in the sensitivity of cardiac cells to adrenergic stimulation during submergence. These results strongly suggest that accentuated antagonism between the two branches of the autonomic nervous system occurs during diving so that parasympathetic influences on the heart predominate and inhibit any chronotropic response to adrenergic stimulation.

Introduction: Elevated resting heart rate (RHR) has been shown to be associated with both all-cause and cardiovascular mortality. Prior studies have provided conflicting estimates of the strength of each association. To explore the relationship between RHR and competing mortality risks, we sought to compare the association between RHR and cardiovascular and non-cardiovascular mortality among participants in the Systolic Blood Pressure Intervention Trial (SPRINT). Methods: Eligible SPRINT participants had baseline RHR, longitudinal follow-up, and were not using beta blockers or non-dihydropyridine calcium channel blockers. Mortality was classified by a treatment-blinded adjudication committee as cardiovascular if secondary to coronary heart disease, stroke, sudden cardiac death, or congestive heart failure. Multivariable Cox proportional hazards models were used to calculate the hazard ratios (HRs) and 95% confidence intervals (95% CI) for cardiovascular and non-cardiovascular mortality, separately, associated with a 10 beats per minute increase in RHR. Results: Among 5,571 eligible SPRINT participants (67.1 ± 9.4 years, 33.8% female, 63.8% white, mean RHR 70.4±11.8 beats per minute) over a median 3.8 years of follow-up, there were 56 cardiovascular deaths and 176 non-cardiovascular deaths. In models adjusted for age, sex, race, prior cardiovascular disease, smoking, systolic blood pressure, creatinine, total cholesterol, high-density lipoprotein cholesterol, and trial treatment assignment, higher RHR (per ten beat-per-minute increase) was associated with both cardiovascular (HR 1.17, 95% CI 1.02-1.35) and non-cardiovascular mortality (HR 1.27, 95% CI 1.13-1.43). Conclusions: Elevated RHR was associated with both cardiovascular and non-cardiovascular mortality, suggesting that RHR may serve as a marker of both global health rather and cardiovascular health. Higher RHR may reflect imbalance in autonomic tone and further studies are needed to explore the mechanisms of these associations.4
