Respiratory Sinus Arrhythmia in Children—Predictable or Random? [PDF]

Frontiers in Cardiovascular Medicine, 2021
Background: Respiratory sinus arrhythmia (RSA) is associated with better health in children.Aim: The study was conducted to analyze the trajectory of RSA in 10-year-olds.Methods: A follow-up study on 120 healthy children (62 boys) aged 10.7 ± 0.5 years ...

Coupling between prefrontal brain activity and respiratory sinus arrhythmia in infants and adults [PDF]

Developmental Cognitive Neuroscience, 2022
Self-regulation is an essential aspect of healthy child development. Even though infants depend on their caregivers for co-regulation during the first years, they begin to gain regulatory abilities through social interactions as well as their own ...

Anthropometric Determinants of Respiratory Sinus Arrhythmia in Children. [PDF]

Int J Environ Res Public Health, 2022
Background: The study was conducted to investigate the implications of anthropometry in school-aged children on the degree of respiratory sinus arrhythmia observed in clinical settings. Methods: In a cohort study, 626 healthy children (52% male) aged 10.8 ± 0.5 years attending primary school in a single town underwent a 12-lead electrocardiogram ...

A study of respiratory sinus arrhythmia and stuttering persistence. [PDF]

J Commun Disord, 2023
The present study investigated potential differences in respiratory sinus arrhythmia between preschool-age children with persisting stuttering, children who recovered from stuttering, and children who do not stutter.Participants were 10 children with persisting stuttering (persisting group), 20 children who recovered from stuttering (recovered group ...

Respiratory Sinus Arrhythmia Mechanisms in Young Obese Subjects

Frontiers in Neuroscience, 2020
Autonomic nervous system (ANS) activity and imbalance between its sympathetic and parasympathetic components are important factors contributing to the initiation and progression of many cardiovascular disorders related to obesity.

Respiratory Sinus Arrhythmia is Mainly Driven by Central Feedforward Mechanisms in Healthy Humans [PDF]

Frontiers in Physiology, 2022
Heart rate variability (HRV) has prognostic and diagnostic potential, however, the mechanisms behind respiratory sinus arrhythmia (RSA), a main short-term HRV, are still not well understood.

Autonomic arousal to emojis: Electrodermal activity and respiratory sinus arrhythmia analysis [PDF]

Physiological Reports
Emojis have become vital in virtual communication, mimicking facial expressions, and gestures to convey emotions. This study investigates their influence on emotional perception and autonomic responses during non‐face‐to‐face interactions.

Effect of Different Pranayamas on Respiratory Sinus Arrhythmia [PDF]

Journal of Clinical and Diagnostic Research, 2016
Introduction: Respiratory Sinus Arrhythmia (RSA) is the differential change of Heart Rate (HR) in response to inspiration and expiration. This is a noninvasive sensitive index of parasympathetic cardiac control.

Methodological issues in the quantification of respiratory sinus arrhythmia [PDF]

Biological Psychology, 2007
Although respiratory sinus arrhythmia (RSA) is a commonly quantified physiological variable, the methods for quantification are not consistent. This manuscript questions the assumption that respiration frequency needs to be manipulated or monitored to generate an accurate measure of RSA amplitude.
