An Overview of HRV Norms and Metrics

Gepubliceerd op: 28-09-2017

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 between consecutive heartbeats called interbeat intervals (IBIs). A healthy heart is not a metronome. The oscillations of a healthy heart are complex and constantly changing, which allow the cardiovascular system to rapidly adjust to sudden physical and psycho-logical  challenges  to  homeostasis.  This  article  briefly  reviews  current  perspectives  on  the mechanisms that generate 24 h, short-term (~5 min), and ultra-short-term (<5 min) HRV,  the  importance  of  HRV,  and  its  implications

Cardiac coherence, self-regulation, autonomic stability, and psychosocial well-being

Gepubliceerd op: 29-09-2014

The ability to alter one’s emotional responses is central to overall well-being and to effectively meeting the demands of life. One of the chief symptoms of events such as trauma, that overwhelm our capacities to successfully handle and adapt to them, is a shift in our internal baseline reference such that there ensues a repetitive activation of the traumatic event. This can result in high vigilance and over-sensitivity to environmental signals which are reflected in inappropriate emotional responses and autonomic nervoussystem dynamics. In this article

Heart rate variability biofeedback: how and why does it work?

Gepubliceerd op: 21-07-2014

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 (Gevirtz,2013). Since conditions as widely varied as asthma and depression seem to respond to this form of cardiorespiratory feedback training, the issue of possible mechanisms becomes more salient.The most supported possible mechanism is the strengthening of homeostasis in the baroreceptor (Vaschillo et al., 2002;Lehrer et al., 2003). Recently, the effect on the vagal afferent

Heart rate variability behavior at different stages of practice in Zen meditation: a study of the system dynamics using multiresolution analysis

The  dynamic  interactions  between  the  sympathetic  and  parasympathetic  branches  of  the  autonomic  nervous system (ANS) are responsible for the oscillations in heart rate known as heart rate variability (HRV). Thus, the importance of HRV as an indirect measure of the autonomic activity is widely known. Meditation is  perhaps  the  best  practice  to  investigate  the  intrinsic  properties  of  the  ANS,  since  it  involves  a  state  of  complete physical immobility and absence of voluntary efforts.
