Does heart rate variability biofeedback improve resting baroreflex gain and peak expiratory flow?
Heart rate variability biofeedback increases resting baroreflex gain and peak expiratory flow, demonstrating neuroplasticity of the baroreflex.
Heart rate variability biofeedback had strong long-term influences on resting baroreflex gain and pulmonary function. It should be examined as a method for treating cardiovascular and pulmonary diseases. Also, this study demonstrates neuroplasticity of the baroreflex.
Lehrer et al. (2003) studied this question.
