“…In large epidemiological studies as ours, it is often not feasible to invasively or pharmacologically measure sympathetic activity and we therefore used surrogate markers of sympathetic activation. However, HR and HR variability are wellestablished parameters of autonomic function (15,16). HR is influenced by sympathetic and parasympathetic outflow to the sinus node, and dominant sympathetic activation over parasympathetic activation results in a higher HR and less variability in HR.…”

Objective: Obesity is associated with sympathetic activation, but the role of different fat depots is unclear. The association between body fat, specifically visceral fat, and electrocardiographic measures of sympathetic activation in a population with structurally normal hearts was investigated. Methods: In this cross-sectional baseline analysis of the Netherlands Epidemiology of Obesity study, body fat percentage was assessed with BIA and abdominal subcutaneous (SAT) and visceral adipose tissue (VAT) with magnetic resonance (MR) imaging. Mean heart rate (HR) and five other electrocardiographic measures of sympathetic activation were calculated. We performed multivariate linear regression analyses. Results: In 868 participants with a mean age(SD) of 55(6) years, BMI of 26(4) kg/m 2 , 47% men, body fat was associated with HR and two other measures of sympathetic activation. Per sex-specific SD total body fat, the difference in HR was 1.9 beats/min (95% CI: 1.0, 2.9; P < 0.001) and per SD waist circumference 2.1 beats/min (95% CI: 1.3, 2.9; P < 0.001). The difference in HR per SD VAT was 2.1 beats/min (95% CI: 1.3, 3.0; P < 0.001). Conclusions: Body fat, especially visceral fat, was associated with electrocardiographic measures of sympathetic activation. Our study implies that already before the onset of cardiovascular disease, excess (visceral) body fat is associated with sympathetic activation.

“…Electrocardiographic markers that are commonly used to study sympathetic activation are heart rate (HR) and HR variability (15,16). Three recent experimental studies showed that the sympathetic overdrive is also reflected in other changes on the standard electrocardiogram (ECG) (17).…”

Purpose -Heart rate variability (HRV) has been studied at rest as a non-invasive tool for the assessment of cardiac autonomic control and, its attenuation is related to cardiovascular risk. However, during exercise, when important neural changes take place, HRV behaviour is not well established. The aim of this investigation was to study the heart rate (HR) and HRV responses during the different metabolic phases of maximal graded exercise in young men.Methods -Seventeen men (age 28±6 years) were submitted to a graded cardiopulmonary exercise test in a cycloergometer (30W/3min). To study HR and HRV (standard-deviation) Métodos -Dezessete homens (28±6 anos) realizaram teste ergoespirométrico máximo em cicloergômetro (30W/ 3min), determinando-se a FC e a VFC (desvio-padrão) através da onda eletrocardiográfica, amplificada e gravada batimento a batimento em computador, numa freqüên-cia da 125Hz (AT/Codas).Resultados [1][2][3][4] . Estudos recentes 5-8 têm demonstrado que a diminuição da VFC está relacionada a um maior índice de morbidade e mortalidade cardiovascular. Por essas razões, muitos autores têm se ocupado em utilizar manobras respiratórias 9 , mudanças de posição 10,11 e bloqueios farmacológicos do sistemas nervosos simpático e parassimpático 10 , na tentativa de investigar a VFC.

“…Nineteen of the respondents refused to carry a Holter recorder. Seventeen shift workers refused to finish the first measurement or to enrol for the second measurement because "it was to cumbersome" (10) or due to due to skin irritation (7). Seven recordings could not be used due to a poor signal to noise ratio (4) or technical malfunction of the equipment (3).…”

24-Hour Heart Rate Variability in Shift Workers: Impact of Shift Schedule: L.G.P.M. van AMELSVOORT, et al. Department of Epidemiology, Maastricht University-Disturbance of the circadian pattern of cardiac autonomic control by working at night when the physiological system anticipates rest could explain part of the elevated cardiovascular risk in shift workers. Analysis of Heart Rate Variability (HRV) is a non-invasive tool to estimate disturbances of the cardiac autonomic control. To assess the influence of working at night on cardiac autonomic control, HRV levels were determined in shift workers. 24-h ECG recordings were made during a day on morning shift and a day on night shift. Within person differences between a morning and a night shift were calculated. Possible modification of the reported effects by the shift schedule was determined. Significantly elevated mean %LF during sleep was found on a day worked on night shift compared with a day on day shift (%LF + 3.04, P<0.01). Type of shift schedule was found to be a significant modifier of this effect. The difference in %LF between the night and day shift for the different shift schedules apart were: + 0.88% for the workers in the fast forward rotating shift, + 3.06% for the fast backward rotating shift, + 6.15% (P<0.001) for the medium speed backward rotating shift and + 1.18% for the shift workers without a regular shift schedule. The results suggest an increased sympathetic dominance during a night shift sleep, indicating an inferior sleep quality. Optimisation of this schedule might diminish this impact and could contribute to a reduction of the cardiovascular disease risk among shift workers.
