Objective We evaluated heart rate variability biofeedback as a method for increasing vagal baroreflex gain and improving pulmonary function among 54 healthy adults. Methods We compared 10 sessions of biofeedback training with an uninstructed control. Cognitive and physiological effects were measured in four of the sessions. Results We found acute increases in low-frequency and total spectrum heart rate variability, and in vagal baroreflex gain, correlated with slow breathing during biofeedback… Expand
Heart rate variability biofeedback: effects of age on heart rate variability, baroreflex gain, and asthma.
TLDR
Age-related attenuation of biofeedback effects on cardiovascular variability does not diminish the usefulness of the method for treating asthma among older patients. Expand
Characteristics of Resonance in Heart Rate Variability Stimulated by Biofeedback
TLDR
How resonance properties of the cardiovascular system mediate the effects of heart rate variability biofeedback is described to provide evidence that resonant oscillations can train autonomic reflexes to provide therapeutic effect. Expand
How Does Heart Rate Variability Biofeedback Work? Resonance, the Baroreflex, and Other Mechanisms
TLDR
The origins of work on heart rate variability biofeedback, and mechanisms for its various effects are reviewed, including direct effects on the baroreflex system and gas exchange efficiency, as well as indirect effects on emotional reactivity and possibly inflammatory activity. Expand
A computational physiology approach to personalized treatment models: the beneficial effects of slow breathing on the human cardiovascular system.
TLDR
Computational physiology may be clinically useful for tailoring heart rate variability biofeedback interventions for the needs of individual patients, and significant improvements in several modeled cardiovascular functions were observed during resonance breathing. Expand
Heart rate variability biofeedback as a behavioral neurocardiac intervention to enhance vagal heart rate control.
TLDR
A novel behavioral neurocardiac intervention, HRV biofeedback, can augment vagal HR regulation while facilitating psychological adjustment to CHD. Expand
Respiratory modulation of cardiovagal baroreflex sensitivity.
TLDR
The lack of change in BRS derived from the modified Oxford method challenges the concept that slow breathing acutely augments arterial baroreflex function in otherwise healthy humans and provides further evidence that spontaneous BRS may not reflect the BRS determined by experimentally driven baroreceptor stimulation. Expand
The effects of slow-paced versus mechanically assisted breathing on autonomic function in fibromyalgia patients
TLDR
Mechanically assisted breathing provided greater benefits in autonomic function than paced breathing in untrained FM patients and controls, and future research will be needed to elucidate the central pathways involved in these autonomic changes. Expand
Influence of inspiratory threshold load on cardiovascular responses to controlled breathing at 0.1 Hz.
TLDR
Results suggest that applying small inspiratory threshold loads during controlled breathing at 0.1 Hz increases cardiac vagal modulation by this breathing exercise, which seems to be mediated by stronger stimulation of the arterial baroreceptors because of larger systolic blood pressure swings along the respiratory cycle.

Biofeedback of Heart Rate Variability and Related Physiology: A Critical Review
TLDR
Evidence suggests HRV biofeedback may result in long-term carry-over effects on baroreflex gain, which is an area most promising for future investigations, and there is ample evidence attesting to efficacy of HRVBiofeedback. Expand

Heart Rate Variability Biofeedback as a Method for Assessing Baroreflex Function: A Preliminary Study of Resonance in the Cardiovascular System
TLDR
High and low target-frequency oscillation amplitudes at specific frequencies could be explained by resonance among various oscillatory processes in the cardiovascular system and changes in heart rate oscillations could not be completely explained by changes in breathing. Expand

TLDR
It is hypothesize that this type of biofeedback exercises the baroreflexes, and renders them more efficient, and is presented for carrying out this method. Expand
Baroreflex gain predicts blood pressure recovery during simulated ventricular tachycardia in humans.
TLDR
These data strongly suggest that arterial baroreflex gain contributes significantly to hemodynamic stability during simulated VT, and may help the clinician tailor therapy directed toward sustained VT. Expand
Arterial pressure ramps provoke linear increases of heart period in humans.
TLDR
The results are similar to those obtained when baroreceptors are stimulated experimentally; they suggest that elevations of arterial pressure, which are preceded by bursts of muscle sympathetic activity, trigger with one heart-beat latency highly linear increases of efferent vagal-cardiac nerve activity.

Respiratory Sinus Arrhythmia Versus Neck/Trapezius EMG and Incentive Inspirometry Biofeedback for Asthma: A Pilot Study
TLDR
The results are consistent with Vaschillo's theory that RSA biofeedback exercises homeostatic autonomic reflex mechanisms through increasing the amplitude of cardiac oscillations through increase in amplitude of Traub-Hering-Mayer waves in heart period. Expand
Baroreflex modulation of blood pressure and heart rate variabilities in rats: assessment by spectral analysis.
TLDR
About 80% of the LF power spectral density of MAP depends on the sympathetic nervous system activity, and the baroreflex accounts for one-half of this power and for the coherence between MAP and HR oscillations in the LF band. Expand
Respiratory modulation of human autonomic rhythms.
TLDR
The results indicate that correlations among autonomic and hemodynamic rhythms vary over time and frequency, and, thus, are facultative rather than fixed. Expand

TLDR
Data suggest that in patients with CHF, slow breathing, in addition to improving oxygen saturation and exercise tolerance as has been previously shown, may be beneficial by increasing baroreflex sensitivity. Expand
Reflex Regulation of Arterial Pressure during Sleep in Man: A Quantitative Method of Assessing Baroreflex Sensitivity
TLDR
It is concluded that the baroreceptor reflex are can be rapidly reset, particularly during sleep, and the lower arterial pressures during sleep may be actively maintained in some subjects by increased baroreflex sensitivity. Expand

TLDR
InterPRETATION ATRAMI provides clinical evidence that after myocardial infarction the analysis of vagal reflexes has significant prognostic value independently of LVEF and of ventricular arrhythmias and that it significantly adds to the prognosticvalue of heart-rate variability. Expand
