Ischemic heart disease (IHD) is rapidly becoming the leading cause of death in developing countries around the world. Psychosocial factors are now recognized as playing a significant and independent role in the development of IHD and its complications. Mental stress has been implicated as a trigger...

Chronic stress is among the most costly health problems in terms of direct health costs, absenteeism, disability, and performance standards. The Reformed Church in America (RCA) identified stress among its clergy as a major cause of higher-than-average health claims and implemented HeartMath (HM) to...

The need for a new health paradigm is irrefutable and well documented. The ever increasing number of complex chronic diseases that cannot be managed by the "pill for an ill" model of traditional healthcare has necessitated a medical paradigm that deals with the underlying causes of complex...

This study assessed personality correlates to electrophysiological measures of prestimulus response (PSR). PSR is the body’s response to a future stimulus prior to experiencing the stimulus. PSR may be an approach to measuring an aspect of intuition. One-hundred candidates for the study comple...

Introduction and Background Since 2007, The Reformed Church in America (RCA) has offered employees the opportunity to participate in the Revitalize You program provided by HeartMath, LLC. McCarthy Actuarial Consulting, LLC (MAC) was retained by RCA to analyze their experience during 2007 and 20...

The purpose of this study was to evaluate the effect of stress management training on quality of life, functional capacity, and heart rate variability in elderly patients with New York Heart Association class I-III congestive heart failure (CHF). While substantial research exists on stress managemen...

The analysis of heart rate variability (HRV), or heart rhythms, provides a reliable measure of autonomic nervous system dynamics that is particularly sensitive to changes in psychophysiological state. Whereas common methods of HRV analysis typically quantify the amount of variability in a given reco...

Objectives This study sought to define the effects of age and gender effects on the normal range of time domain heart rate variability (HRV) over nine decades in healthy subjects. Background Low HRV is considered an independent marker of mortality risk. However, the age-related decline in HRV may li...

Chronic fatigue syndrome (CFS) is a medically unexplained disorder characterized by chronic, disabling fatigue, muscle pain, impaired concentration and a variety of neurobiological symptoms that make everyday activities extremely difficult. While it has been suggested that patients with CFS may have...

This work utilizes the measurement of heart rate variability (HRV) as a vehicle to show that continued practice of certain specific techniques involving an intentional shift of focus to the area of the heart, and invoking specific feeling states such as love and appreciation, automatically manifests...
