Journal of Physiology, 2019 Respiratory sinus arrhythmia is physiological pacing of the heart that disappears in cardiovascular disease and is associated with poor cardiac prognosis. In heart failure, cardiac pacing has little, if any, variation in rate at rest.

Resting Respiratory Sinus Arrhythmia in Suicide Attempters
Psychophysiology, 2017 Although suicide attempts (SA) occur across a broad range of diagnoses as well as in the absence of a diagnosable disorder, most studies to date have focused on them within a single, specific disorder. Consistent with the NIMH RDoC initiative to identify

Brainstem sources of cardiac vagal tone and respiratory sinus arrhythmia
Journal of Physiology, 2016 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 phase of ...

Optimal Multi-Stage Arrhythmia Classification Approach
Scientific Reports, 2020 Arrhythmia constitutes a problem with the rate or rhythm of the heartbeat, and an early diagnosis is essential for the timely inception of successful treatment. We have jointly optimized the entire multi-stage arrhythmia classification scheme based on 12-

Respiratory sinus arrhythmia as a potential measure in substance use treatment-outcome studies
Addiction, 2016 Background and Aims Dysfunction of physiological regulation systems may underlie the disrupted emotional and self-regulatory processes among people with substance use disorder (SUD). This paper reviews evidence as to whether respiratory sinus arrhythmia (

Current Opinion in Psychology, 2015 In the past two decades, respiratory sinus arrhythmia (RSA)—an index of parasympathetic nervous system (PNS)-mediated cardiac control—has emerged as a reliable peripheral biomarker of emotion regulation (ER). Reduced RSA and excessive RSA reactivity (i.e.
