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.

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 in Chagas disease [PDF]
Autonomic Neuroscience, 2014 We applied the respiratory sinus arrhythmia (RSA) quantification algorithm to 24-hour ECG recordings of Chagas disease (ChD) patients with (G1, n=148) and without left ventricular dysfunction (LVD) (G2, n=33), and in control subjects (G0, n=28). Both ChD groups displayed a reduced RSA index; G1=299 (144-812); G2=335 (162-667), p=0.011, which was ...

In vivo dose measurement using TLDs and MOSFET dosimeters for cardiac radiosurgery. [PDF]
, 2012 In vivo measurements were made of the dose delivered to animal models in an effort to develop a method for treating cardiac arrhythmia using radiation. This treatment would replace RF energy (currently used to create cardiac scar) with ionizing radiation.

The effect of adenotonsillectomy for childhood sleep apnoea on cardiorespiratory control
ERJ Open Research, 2016 The efficacy of adenotonsillectomy for relieving obstructive sleep apnoea symptoms in children has been firmly established, but its precise effects on cardiorespiratory control are poorly understood.

The effect of heart rate variability biofeedback training on stress and anxiety: a meta-analysis [PDF]
, 2017 BACKGROUND: Some evidence suggests that heart rate variability (HRV) biofeedback might be an effective way to treat anxiety and stress symptoms. To examine the effect of HRV biofeedback on symptoms of anxiety and stress, we conducted a meta-analysis of ...
