Respiratory sinus arrhythmia in diabetic neuropathy [PDF]

Diabetologia, 1983
Heart rate variation was measured at different rates of regular deep breathing (2.5 to 13 breaths/min) in 11 normal subjects and 13 diabetic patients with neuropathy, defined clinically by the absence of both ankle jerks or the presence of autonomic symptoms. Subjects were divided into those above and below 30 years old.

Bidirectional Cardio-Respiratory Interactions in Heart Failure

Frontiers in Physiology, 2018
We investigated cardio-respiratory coupling in patients with heart failure by quantification of bidirectional interactions between cardiac (RR intervals) and respiratory signals with complementary measures of time series analysis.

Respiratory Sinus Arrhythmia Mediates the Relation Between “Specific Math Anxiety” and Arithmetic Speed

Frontiers in Psychology, 2021
There is a growing consensus that math anxiety highly correlates with trait anxiety and that the emotional component elicited by math anxiety affects math performance. Yet few studies have examined the impact of “specific math anxiety” (high math anxiety

Exercise-induced ventricular arrhythmias and vagal dysfunction in Chagas disease patients with no apparent cardiac involvement

Revista da Sociedade Brasileira de Medicina Tropical, 2015
INTRODUCTION : Exercise-induced ventricular arrhythmia (EIVA) and autonomic imbalance are considered as early markers of heart disease in Chagas disease (ChD) patients. The objective of the present study was to verify the differences in the occurrence of

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.

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 ...

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.

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.

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
