The use of heart rate variability (HRV) in research has been greatly popularized over the
past decades due to the ease and affordability of HRV collection, coupled with its clinical …

Clinical research on the beneficial effects induced by slow-paced breathing has been
increasingly extended in the past twenty years. Improvements in cardiovascular functioning …

We performed a systematic and meta analytic review of heart rate variability biofeedback
(HRVB) for various symptoms and human functioning. We analyzed all problems addressed …

Healthy biological systems exhibit complex patterns of variability that can be described by
mathematical chaos. Heart rate variability (HRV) consists of changes in the time intervals …

Contemplative practices, such as meditation and yoga, are increasingly popular among the
general public and as topics of research. Beneficial effects associated with these practices …

Heart rate variability (HRV), the change in the time intervals between adjacent heartbeats, is
an emergent property of interdependent regulatory systems that operate on different time …

In recent years there has been substantial support for heart rate variability biofeedback
(HRVB) as a treatment for a variety of disorders and for performance enhancement. Since …

The number of publications investigating heart rate variability (HRV) in psychiatry and the
behavioral sciences has increased markedly in the last decade. In addition to the significant …

Heart rate variability (HRV) represents fluctuations in the time intervals between successive
heartbeats, which are termed interbeat intervals. HRV is an emergent property of complex …

Research on brain oscillations has brought up a picture of coupled oscillators. Some of the
most important questions that will be analyzed are, how many frequencies are there, what …
