“…The lack of association between PLR and HRV can be further corroborated by the different gender effect in PLR and HRV parameters. In agreement with a previous report by Krishnan et al (2009) in a large group of children of similar age range, our data showed that girls had a significantly higher heart rate than boys. A higher heart rate indicates stronger sympathetic influence .…”

Simultaneously measured pupillary light reflex and heart rate variability in healthy children

We investigated the potential interrelationship between two measures of autonomic nervous system: pupillary light reflex (PLR) and heart rate variability (HRV), in healthy children of 8–16 years old. PLR was measured at both dark- and light-adapted conditions with various stimulation intensities. Simultaneously measured HRV was obtained in five different PLR testing phases: before PLR test, light-adapted PLR test, dark adaptation, dark-adapted PLR test, and after PLR test. The frequency domain HRV parameters measured during PLR test were significantly different from those measured during rest. Both regression analysis and factor analysis indicated that PLR and HRV parameters were not correlated, which suggests that they may provide complementary assessment of different aspects of the overall autonomic nervous system.

“…In the other study, girls (aged (9 ± 0.25) years) showed higher resting heart rate but HRV were not different between genders [25]. Our study also showed no difference between genders.…”

Background: The child's central nervous system develops with aging, and heart rate variability (HRV), which is controlled by the brain, differs from that of adults. We investigated changes in HRV during sevoflurane anesthesia in children. Methods: One 138 children aged from 2 -12 years without major underlying problems were enrolled. During maintenance with 2 -2.5 vol% sevoflurane anesthesia, electrocardiographic data were obtained and power spectral analysis, approximate entropy (ApEn) or Hurst exponent were analyzed and compared in three groups (age 2 -5 years, 6 -9 and 10 -12 years of age). Results: The RR interval increased with aging, but low-frequency powers did not. Highfrequency power was greater in the oldest children (P < 0.05), while ApEn and Hurst exponents were lower (P < 0.05). Conclusion: Change in HRV is one of the characteristics of development in children.

Gender differences in the relationship between heart rate control and adiposity in young children: a cross-sectional study (EarlyBird 33)

Abstract: The data suggest early gender differences in predictors of cardiac autonomic control. Pubertal staging was not undertaken in this study, and we plan to evaluate this in future studies to further clarify these associations.
