**9. Conclusions**

The HeartMath Institute formally reviews its activities in the form of annual reports. A variety of these activities regularly feature in update formal reviews by independent researchers, more of which are needed [49,50]. The specific goal of this study was to provide an inclusive, update, overview of HeartMath as an integrative, personal, social, and global healthcare system. Various research studies have consistently endorsed the practical value of diverse HeartMath tools, techniques, and electronics as excellent in transforming negativity into positivity and renewing the patterns of energy typically experienced in the forms of such feelings as peace and love. Considerable scientific evidence points to vast, energetic, interconnectivity at the human, planetary, and solar systemic levels. It is reasonable to conclude that the many HeartMath practitioners and GCI ambassadors from over 150 countries [2,3] who practice heart focused care, compassion, and love with an aim towards improving global coherence provide substantial human and planetary healthcare.

The present study has provided an overview of HeartMath as a coherent, integral heart-based healthcare system. Various forms of evidence have been presented to support this contention. There does not appear to be any contradictory evidence to this effect, although further gold-standard, empirically orientated, randomized controlled trials are needed [50]. Future conceptual, theoretical, and paradigmatic studies are also needed. In practical healthcare terms, positive emotions and heart focused breathing may facilitate vast interconnectivity. In addition to the pursuit of scientific programs and interventions, global healthcare amongst the general public needs vigorous promotion, especially when aimed towards facilitating the coherent collaboration of all related healthcare organizations and their associated stakeholders.
