    Published in Applied Psychophysiology and Biofeedback, Vol. 45 (3), pp. 109-129

    Methodology

    Meta-analysis of controlled trials of heart rate variability biofeedback measuring vagally mediated HRV indices and stress outcomes.

    Key Findings

    Biofeedback significantly increased vagally mediated heart rate variability and reduced self-reported stress and anxiety.

    Conclusions

    Direct vagal training reliably raises parasympathetic tone.

    Limitations

    Blinding difficult; heterogeneous protocols.

    Outcomes Measured
