Cardiopulmonary Resonance Function and Indices—A Quantitative Measurement for Respiratory Sinus Arrhythmia

Frontiers in Physiology, 2020
Respiratory sinus arrhythmia (RSA) represents a physiological phenomenon of cardiopulmonary interaction. It is known as a measure of efficiency of the circulation system, as well as a biomarker of cardiac vagal and well-being.

Cyclical Modulation of Human Ventricular Repolarization by Respiration

Frontiers in Physiology, 2012
Background: Respiratory modulation of autonomic input to the sinus node results in cyclical modulation of heart rate, known as respiratory sinus arrhythmia.

Linear and Non-linear Quantification of the Respiratory Sinus Arrhythmia Using Support Vector Machines

Frontiers in Physiology, 2021
Respiratory sinus arrhythmia (RSA) is a form of cardiorespiratory coupling. It is observed as changes in the heart rate in synchrony with the respiration. RSA has been hypothesized to be due to a combination of linear and nonlinear effects.

Evaluating Respiratory Sinus Arrhythmia as a Mediator of Relations between Minority Stress and Depressive Symptoms Among Sexual Minorities [PDF]

, 2020
Compared with heterosexuals, those with sexual minority identities (e.g., lesbian, gay, bisexual) are at significantly greater risk of psychopathology, including depression—the most common mental health disorder in the general population. A large body of

Respiratory sinus arrhythmia is reduced in adolescent major depressive disorder

European Journal of Medical Research, 2009
Objective Although the emotion regulatory difficulties in patients with major depressive disorder (MDD) are predicted to associate with impaired cardiovascular autonomic regulation, the changes of cardiac vagal regulation in MDD are incompletely ...

Awe proneness links RSA and trait creativity in dyslexia

Journal of Creativity
The parasympathetic nervous system promotes positive emotions, such as awe, that foster creativity. Resting respiratory sinus arrhythmia, a parasympathetic measure of heart rate variability, is elevated in children with dyslexia, but whether this ...

Cardiorespiratory and autonomic-nervous-system functioning of drug abusers treated by Zen meditation

Journal of Traditional and Complementary Medicine, 2019
Addicted drugs like nicotine affect autonomic nervous system that results in arrhythmia and other cardiovascular diseases. Notable effects of Zen meditation on autonomic nervous system have been reported during the past decade. Holistic Detox Association

Heart Rate Monitoring During Different Lung Volume Phases Using Seismocardiography

, 2018
Seismocardiography (SCG) is a non-invasive method that can be used for cardiac activity monitoring. This paper presents a new electrocardiogram (ECG) independent approach for estimating heart rate (HR) during low and high lung volume (LLV and HLV ...
