Heart Rate Variability, Health and Well-Being: A Systems Perspective

The development of a new tool, analytic device, or approach frequently facilitates rapid growth in scientific understanding, although the process is seldom linear. The study of heart rate variability (HRV) defined as the extent to which beat-to-beat variation in heart rate varies, is a rapidly maturing paradigm that integrates health and wellness observations across a wide variety of biomedical and psychosocial phenomena and illustrates this nonlinear path of development. The utility of HRV as an analytic and interventive technique goes far beyond its original application as a robust predictor of sudden cardiac death. This Research Topic aims to provide a conceptual

Methods: Study participants were asked to complete the Personal and Organizational


Heart Rate Variability: New Perspectives on Assessment of Stress and Health Risk at the Workplace

Published on: 04-02-2019

Introduction: Cardiovascular diseases are the highest cause of death in the world. Many of these deaths may be workplace related. Long hours at work seem to be influencing the increased risks of heart diseases. Workplace stress can be defined as the “discrepancies between the physiological demands within a workplace and the inability of employees to either manage or cope with such work demands.” The varied nature and perception of stress are exemplified from literature that shows stress being either a stimulus, or a response, or a stimulus–


Combining Biofeedback with Stress Management Interventions: A Systematic Review of Physiological and Psychological Effects

Published on: 02-01-2019

Current mental healthcare systems experience difficulties meeting the challenges of a growing population with elevated stress symptoms. Outpatient stress management interventions have already proven to be effective in routine care and recent technological advances now allow to expand such interventions, for example by adding a physiological component like biofeedback. Adding biofeedback to stress management interventions appears promising, but there is a lack of insight into the general conceptualization and evaluation of the resulting
