Recent studies have found a significant association between PTSD and low heart rate variability (HRV), a biomarker of autonomic dysregulation. Research indicates that respiratory sinus arrhythmia (RSA) biofeedback increases HRV while reducing related pathological symptoms. This controlled pilot study compared RSA biofeedback to progressive muscle relaxation (PMR) as adjunctive interventions for 38 persons with PTSD symptoms in a residential treatment facility for a substance use disorder. Both… Expand
Heart Rate Variability (HRV) and Posttraumatic Stress Disorder (PTSD): A Pilot Study
TLDR
The results indicated that HRV biofeedback significantly increased the HRV while reducing symptoms of PTSD, however, the TAU had no significant effect on either HRV or symptom reduction. Expand
Respiratory sinus arrhythmia biofeedback therapy may increase heart rate variability activity and decrease reactivity in male patients with major depressive disorder: A pilot study
TLDR
The study results highlight the potential rôle of RSA-BT on the increased HRV activity with a shift sympathetic predominance at rest and decreased HRV reactivity toward parasympathetic dominance during mental stress in patients with depression, which is not related to the effects of antidepressant or benzodiazepine medication. Expand
Heart Rate Variability and Posttraumatic Stress Disorder
The psychophysiology of posttraumatic stress disorder (PTSD) points towards autonomic dysregulation—specifically, elevated sympathetic response and attenuated parasympathetic response. In view ofExpand
Pilot Study of a Single Session Heart Rate Variability Biofeedback Intervention on Veterans’ Posttraumatic Stress Symptoms
TLDR
HRVB significantly reduced global posttraumatic stress symptoms, whereas diaphragmatic breathing alone did not, and veterans found the approach acceptable, as demonstrated by a high degree of adherence with prescribed practice, low study attrition, and continued use over time. Expand

TLDR
Respiration, electroencephalography and heart rate variability and peak alpha frequency are sensitive to PTSD status and may be potential biofeedback parameters for future PTSD clinical trials. Expand
Effects of Heart Rate Variability Biofeedback in Subjects with Stress-Related Chronic Neck Pain: A Pilot Study
TLDR
Improvement in perceived health over a 10 week intervention with HRV-biofeedback in subjects with chronic neck-pain is indicated, and it is suggested that this intervention protocol is suitable for a larger controlled trial. Expand
Relaxation training assisted by heart rate variability biofeedback: Implication for a military predeployment stress inoculation protocol.
TLDR
Examination of PRESTINT protocol found it to be appropriate for efficiently teaching self-help skills to reduce the psychological harm following trauma exposure by increasing the capacity for parasympathetically modulated reactions to stress and providing a coping tool for use following a stressful situation. Expand
Alcohol Use Disorder Moderates the Effect of Age on Heart Rate Variability in Veterans With Posttraumatic Stress Disorder
TLDR
Findings support HRV as a biomarker of PTSD and extend research by demonstrating the complex relationship between PTSD and HRV in the context of co-occurring AUD. Expand
The Application of Heart Rate Variability Biofeedback to Medical and Mental Health Disorders
TLDR
Outcome studies on HRVB offers promising therapeutic benefit for any medical or mental health disorder known to be accompanied by autonomic nervous system dysregulation, and the authors review outcome studies on a sampling of common disorders. Expand
Resting respiratory sinus arrhythmia and posttraumatic stress disorder: A meta-analysis
TLDR
Overall, there is a small but reliable association between PTSD and lower resting RSA, providing support for further research examining the complex relationship between parasympathetic activity and PTSD. Expand

Low respiratory sinus arrhythmia and prolonged psychophysiological arousal in posttraumatic stress disorder: heart rate dynamics and individual differences in arousal regulation
TLDR
This study is the first to find decreased RSA in response to a traumatic reminder and an association between low baseline RSA and sustained conditioned arousal in PTSD, which may account for deficient arousal and emotion regulation capacities often observed in PTSD. Expand
Normalization of heart rate variability in post-traumatic stress disorder patients following fluoxetine treatment: preliminary results.
TLDR
The preliminary results show that the HRV parameters indicating autonomic dysregulation, which characterize PTSD patients at rest, are normalized in responding patients by use of SSRIs. Expand
Autonomic dysregulation in panic disorder and in post-traumatic stress disorder: application of power spectrum analysis of heart rate variability at rest and in response to recollection of trauma or panic attacks
TLDR
HRV analysis demonstrates significant differences in autonomic regulation of PTSD and PD patients compared to each other and to control subjects, and may augment biochemical studies of peripheral measures in these disorders. Expand
Preliminary Results of an Open Label Study of Heart Rate Variability Biofeedback for the Treatment of Major Depression
TLDR
HRV biofeedback appears to be a useful adjunctive treatment for the treatment of MDD, associated with large acute increases in HRV and some chronic increases, suggesting increased cardiovagal activity. Expand
Vagal modulation of responses to mental challenge in posttraumatic stress disorder
TLDR
Trauma survivors who develop PTSD differ from those who do not in the extent to which their heart rate response to challenge is controlled by vagal activity, and responses to challenge in PTSD may be mediated by nonvagal, possibly sympathetic mechanisms. Expand
Analysis of heart rate variability in posttraumatic stress disorder patients in response to a trauma-related reminder
TLDR
Standardized heart rate analysis carried out in 9 posttraumatic stress disorder patients at rest demonstrated clear-cut evidence of a baseline autonomic hyperarousal state, and the lack of response to the stress model applied in the study appears to imply that PTSD patients experience so great a degree of autonomichyperactivation at rest, that they are unable to marshal a further stressresponse to the recounting of the triggering trauma.

A Meta-Analytic Examination of Basal Cardiovascular Activity in Posttraumatic Stress Disorder
TLDR
A positive association between PTSD and basal cardiovascular activity is found and the results suggest that PTSD is associated with elevations in blood pressure; however, the effect sizes were smaller in magnitude than those obtained for heart rate. Expand
Effect of Cognitive Behavioral Therapy on Heart Rate Variability During REM Sleep in Female Rape Victims with PTSD
TLDR
A remission in PTSD symptoms following CBT accompanied a reduction in the HRV indicator of sympathetic predominance in REM sleep, which led to a remission in symptoms following cognitive–behavioral therapy. Expand
A multisite study of initial respiration rate and heart rate as predictors of posttraumatic stress disorder.
TLDR
Elevated heart rate and respiration rate are predictors of subsequent PTSD and the need for future research into secondary prevention strategies that reduce acute arousal immediately after trauma and may limit PTSD development in some individuals is underscore. Expand
Preliminary evidence of parasympathetic influence on basal heart rate in posttraumatic stress disorder.
TLDR
These findings suggest that a substantial proportion of those with PTSD may not have elevated basal HRs, and among those who do exhibit elevated HR, there may be a parasympathetic contribution that is independent of any sympathetic one. Expand
