Cyclical Modulation of Human Ventricular Repolarization by Respiration

open access: yesFrontiers 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.

Awe proneness links RSA and trait creativity in dyslexia

open access: yesJournal 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 ...

Heart Rate Monitoring During Different Lung Volume Phases Using Seismocardiography

open access: yes, 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 ...

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

open access: yesJournal 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

QUANTIFICATION OF RESPIRATORY SINUS ARRHYTHMIA WITH HIGH-FRAMERATE ELECTRICAL IMPEDANCE TOMOGRAPHY

open access: yesActa Polytechnica, 2013
Respiratory Sinus Arrhythmia, the variation in the heart rate synchronized with the breathing cycle, forms an interconnection between cardiac-related and respiratory-related signals.

Improved integrate-and-fire model for RSA

open access: yesMathematical Biosciences and Engineering, 2007
A simple operational model of heart rate variability is described, accounting in particular for the respiratory sinus arrhythmia, and is fitted to some interbeat interval sequences recorded from normal subjects at rest. The model performance is evaluated
