Heart rate variability (HRV) refers to the beat-to-beat alteration in cardiac cycle length. The objective is to study effect of posture on HRV. Five minutes ECG of children (12 females and 20 males) with mean height 138.88 +/- 11.88 cm, weight 27.66 +/- 5.87 kg and BMI 16.11 +/- 1.38 kg/m(2) were recorded in supine, sitting and standing position. HRV parameters were compared by one-way ANOVA and Bonferroni test. Standing decreases Mean interval between successive RR waves (622.69 +/- 83.24 ms… Expand
Postural Changes on Heart Rate Variability among Older Population: A Preliminary Study
Sitting may not be the best position for older individuals in the assessment of their autonomic responses, whereas the supine position is recommended as the baseline posture in the old-age population. Expand
Time-domain HRV Analysis of ECG Signal under Different Body Postures
The frequency-domain analysis result suggests, supine posture has a higher LF/HF ratio i.e. higher sympathetic influence and hence supine has a better resting condition than sitting and standing. Expand
Heart Rate Variability in Children Submitted to Surgery
It is demonstrated that surgery has impact on Autonomic Nervous System function in healthy children but, independently of anesthetic drugs, type of surgery, age and existence of pain 60 minutes after surgery no difference in HRV measures was found and autonomic homeostasis was re-established.

Multifractal Correlation Study Between Posture and Autonomic Deregulation Using ECG and Blood Pressure Data
This chapter presents analysis of non-linear time series of ECG and arterial blood pressure data from a new perspective using state-of-the-art non- linear technique for assessment of cardiac disorder induced by different human posture. Expand

Effect of posture on heart rate variability spectral measures in children and young adults with heart disease.
The results demonstrate that in this age range, the response to posture is not unique because of the difference in high-frequency power, which implies a variety of vagal modulations of heart rate. Expand
Heart-rate variability in children. Spectral analysis of developmental changes between 5 and 24 years.
Spectral analysis of heart rate appears a promising technique for investigating the development of neural control of the heart and suggests that many children have a significant decrease in sympathetic activity between 5 and 10 years of age and possibly a slight decrease in parasympathetic activity. Expand
Effect of standing on short term heart rate variability across age
Heart rate variability responses to standing were highest in the young adults, followed by the children and the elderly, although the differences between theYoung adults and children were not significant, and more studies are needed to characterize HRV responses to posture in children. Expand
Beat‐to‐beat blood pressure and heart rate responses to active standing in Japanese children
Results indicated that pubertal children were more susceptible to orthostatic stress, probably due to abnormal BP responses in the initial phase of active standing, which seemed to reflect enhanced cardiopulmonary reflexes and diminished sympathetic activation associated with the age. Expand
Correlates of the shift in heart rate variability with postures and walking by time-frequency analysis
The results based upon eighteen subjects performing four sequential 5-min physical activities showed that the high-frequency heartbeat fluctuations during supine and sitting were significantly larger than during standing, and that the ratio of low-to-high-frequency fluctuation during standing was significantly higher than during supines and sitting. Expand
Aging of modulation of heart rate.
It is concluded that the influence of the two major mechanisms that modulate heart rate decline at significantly different rates with aging. Expand
Circulatory response to postural change in healthy male subjects in relation to age.
It is concluded that the circulatory adjustment to the stress of postural change differs markedly between young and elderly subjects and in healthy old subjects marked postural hypotension appears to be rare. Expand
Individual recognition by heart rate variability of two different autonomic profiles related to posture.
The combined use of spectral methodology and forecasting analysis has revealed an information content embedded, per se, in a short series of RR intervals capable of recognizing, individual by individual, two different autonomic profiles related to posture. Expand
Effect of age on long-term heart rate variability.
Sleep ULF power is not significantly affected by age, whereas VLF, LF and HF powers and fractal dimensions of heart rate significantly decrease with age during awake as well as sleep periods. Expand
Blood pressure modulation by central venous pressure and respiration. Buffering effects of the heart rate reflexes.
Both slow changes of BP induced by variations of CVP and more rapid changes induced by ILV are actively buffered by heart rate reflexes, suggesting that neurally mediated changes in HR may offset mechanical effects caused by respiration. Expand
