Heart rate variability biofeedback: how and why does it work?
TLDR
This article reviews the effect on the vagal afferent pathway to the frontal cortical areas has been proposed and other possible mechanisms that might explain the positive effects of HRVB.
The Effects of Respiratory Sinus Arrhythmia Biofeedback on Heart Rate Variability and Posttraumatic Stress Disorder Symptoms: A Pilot Study
TLDR
Preliminary support is provided for the efficacy of RSA biofeedback in improving physiological and psychological health for individuals with PTSD in a residential treatment facility for a substance use disorder.
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.
The Promise of Heart Rate Variability Biofeedback: Evidence-Based Applications
TLDR
Empirical evidence from multiple sources is presented from the point of view of possible mechanisms of effect in heart rate variability biofeedback.
The Effect of Biofeedback on Function in Patients with Heart Failure
TLDR
A combination of HRV biofeedback and breathing retraining may improve exercise tolerance in patients with HF with an LVEF of 31% or higher and cardiorespiratory biofeedbacks has the potential to improve cardiac mortality and morbidity in HF patients.
The treatment of fear of flying: a controlled study of imaginal and virtual reality graded exposure therapy
TLDR
Results showed virtual reality graded exposure therapy was more effective than IET in the treatment of flying and suggests that physiological feedback may add to the efficacy of VR treatment.
Associations among pain, PTSD, mTBI, and heart rate variability in veterans of Operation Enduring and Iraqi Freedom: a pilot study.
TLDR
The preliminary findings support the high prevalence of depressed HRV and P3 among veterans seen in a level II Polytrauma Center and suggest a possible synergistic effect of pain, PTSD, and mTBI on depressedHRV.
Effects of Respiratory Sinus Arrhythmia Biofeedback Versus Passive Biofeedback Control
TLDR
Preliminary results suggest that brief relaxation training can reduce state anxiety but that RSA biofeedback appears to have added benefits in reducing state anxiety and HR stress reactivity compared to passive relaxation techniques.
