Respiratory sinus arrhythmia (RSA) is an index of cardiovagal regulation, emotional and
cognitive processing. RSA is quantified using heart rate variability (HRV) spectral analysis at …

Respiratory sinus arrhythmia (RSA) has been widely used as a measure of the cardiac vagal
control in response to stress. However, RSA seems not to be a generalized indicator …

Researchers are interested in respiratory sinus arrhythmia (RSA) as an index of cardiac
vagal activity. Yet, debate exists about how to account for respiratory influences on …

Ventilation related heart rate oscillations–respiratory sinus arrhythmia (RSA)–originate in
human from several mechanisms. Two most important of them–the central mechanism …

A method for the accurate time-domain characterization of respiratory sinus arrhythmia
(RSA) pattern is presented and applied to two groups of healthy subjects to lay the baseline …

Three algorithms for assessment of respiratory sinus arrhythmia (RSA) have been
evaluated: cross-correlation function, histogram analysis and regression plot. The algorithms …

Fourier-based techniques are mathematically noncausal and are therefore limited in their
application to feedback-containing systems, such as the cardiovascular system. In this study …

To investigate the interindividual differences in respiratory sinus arrhythmia (RSA),
recordings of ventilation and electrocardiogram were obtained from 12 healthy subjects for …

Respiratory sinus arrhythmia (RSA) represents a physiological phenomenon of
cardiopulmonary interaction. It is known as a measure of efficiency of the circulation system …

Although respiratory sinus arrhythmia (RSA) is a commonly quantified physiological
variable, the methods for quantification are not consistent. This manuscript questions the …
