Psychophysiological Training of Operators in Adaptive Biofeedback Cardiorhythm Control [PDF]

, 2006
A new individual computerized technique for psychophysiological training of operators before performing psychomotor activity on a computer model (psychomotor concentration and spatial orientation test) was developed.

Respiratory Sinus Arrhythmia During Speech Production [PDF]

Journal of Speech, Language, and Hearing Research, 2003
The amplitude of the respiratory sinus arrhythmia (RSA) was investigated during a reading aloud task to determine whether alterations in respiratory control during speech production affect the amplitude of RSA. Changes in RSA amplitude associated with speech were evaluated by comparing RSA amplitudes during reading aloud with those obtained during rest

Trendelenburg positioning with or without norepinephrine infusion for haemodynamic support in anaesthetised hypovolemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Intraoperative haemorrhage during equine anaesthesia is a rare but potentially fatal complication requiring prompt haemodynamic support. Postural manoeuvres such as Trendelenburg (TL) positioning and vasopressor support augment venous return and improve cardiac output (CO), yet their efficacy in anaesthetised hypovolemic horses ...

Free‐Breathing 3D Whole Heart and Aorta Cine MRI Without Contrast Agent—Comparison to Clinical Standard

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The demand for cardiac MRI is increasing with the growing burden of cardiovascular disease. However, conventional protocols require sequential acquisitions for multi‐breath‐hold 2D cine and 3D MR angiography (MRA), which is time‐consuming.

Brainstem Sources of Cardiac Vagal Tone and Respiratory Sinus Arrhythmia [PDF]

, 2016
KEY POINTS: Cardiac vagal tone is a strong predictor of health, although its central origins are unknown. Respiratory‐linked fluctuations in cardiac vagal tone give rise to respiratory sinus arryhthmia (RSA), with maximum tone in the post‐inspiratory ...

Postoperative Weight Gain, Due to Fluid Retention After Ovarian Cancer Surgery—How Much Is too Much?

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background and Objectives Postoperative complications after cytoreductive surgery in ovarian cancer patients are associated with impaired survival. Here, we investigated the association between postoperative weight gain due to fluid retention and the development of complications and anastomotic leakage (AL).

Dyadic Coping, Respiratory Sinus Arrhythmia, and Depressive Symptoms Among Parents of Preschool Children

Frontiers in Psychology, 2018
Respiratory sinus arrhythmia (RSA) is a biomarker of cardiac vagal tone that has been linked to social functioning. Recent studies suggest that RSA moderates the impact of interpersonal processes on psychosocial adjustment.

Point process time–frequency analysis of dynamic respiratory patterns during meditation practice [PDF]

, 2011
Respiratory sinus arrhythmia (RSA) is largely mediated by the autonomic nervous system through its modulating influence on the heart beats. We propose a robust algorithm for quantifying instantaneous RSA as applied to heart beat intervals and respiratory
