The respiratory component of heart rate variability (respiratory sinus arrhythmia, RSA) has
been associated with improved pulmonary gas exchange efficiency in humans via the …

Numerous methods for enhancing consciousness and well-being emphasize the role of
breathing. For the first time, we have investigated the link between body rhythms and slow …

The application of a noncontact physiological recording technique, based on the method of
laser Doppler vibrometry (LDV), is described. The effectiveness of the LDV method as a …

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 …

OBJECTIVE: An important procedure in diagnosing stress-related disorders caused by
dysfunction in the interaction of the heart with breathing, ie, respiratory sinus arrhythmia …

OBJECTIVES: To assess the effects of pursed-lip breathing (PLB) at rest on the behavior of
heart rate (HR) and its variability, and on variations in blood pressure (BP), respiratory rate …

The cardiac and respiratory systems can be viewed as two self-sustained oscillators with
various interactions between them. In this study, the cardiorespiratory phase synchronization …

The jeju is a teleost fish with bimodal respiration that utilizes a modified swim bladder as an
air-breathing organ (ABO). Like all air-breathing fish studied to date, jeju exhibit pronounced …

Respiratory sinus arrhythmia (RSA) is related to cardiac vagal outflow and the respiratory
pattern. Prior infant studies have not systematically examined respiration rate and tidal …

Strong cognitive regulation is advantageous for flexible, responsive parenting. Optimal
cognitive regulation is reliant on associations between physiological mechanisms of central …
