Respiratory sinus arrhythmia as a measure of cognitive workload
International Journal of Psychophysiology, 2012The current standard for measuring cognitive workload is the NASA Task-load Index (TLX) questionnaire. Although this measure has a high degree of reliability, diagnosticity, and sensitivity, a reliable physiological measure of cognitive workload could provide a non-invasive, objective measure of workload that could be tracked in real or near real-time ...

Interoception and respiratory sinus arrhythmia in gambling disorder
Psychophysiology, 2019AbstractGambling has longstanding links with excitement and physiological arousal, but prior research has not considered (a) gamblers’ ability to detect internal physiological signals, or (b) markers of parasympathetic functioning. The present study measured interoception in individuals with gambling disorder, using self‐report measures and a heartbeat

Paradoxical respiratory sinus arrhythmia in the anesthetized rat
Autonomic Neuroscience, 2005This study examines respiratory sinus arrhythmia (RSA) in the isoflurane-anesthetized rat. In fifteen female Sprague-Dawley rats, we recorded continuous ECG and respiratory airflow before and after bilateral vagotomy. RSA was assessed using power spectral analysis and by plotting the normalised changes in heart period as a function of the time during ...

Acute Intracranial Lesions and Respiratory Sinus Arrhythmia
Archives of Neurology, 1992We studied the effects of acute intracranial lesions on the respiratory sinus arrhythmia (RSA) with the use of computerized measurements of the ratio of expiratory to inspiratory R-R intervals. The RSA was reduced below the 95th percentile for age in 20 of 27 patients, an average of 2 days after an acute event.

Respiratory Sinus Arrhythmia in Cluster Headache Syndrome
Headache: The Journal of Head and Face Pain, 1993SYNOPSIS Respiratory sinus arrhythmia is regarded as indicative of cardiac vagal integrity. A ratio of the longest R‐R interval to the shortest R‐R interval during deep breathing test (E:I ratio) was calculated in controls (n=49), cluster headache (n=33) and CPH (n=4) patients, E:I ratio decreased with age but was
