Integrative Heart-Assisted Healing

Abstract photo
By combining contemporary biophysics and cardiovascular psychophysiology with cognitive and affective neuroscience, it is possible to create an integrative heart-focused psychotherapeutic technique for effectively treating stress related disorders, including grief.
Ongoing clinical as well as basic scientific research is investigating HAT (Heart Assisted Therapy).



HAT (Heart Assisted Therapy) is an integrative, humanistic, and mindfulness-enhancing approach to psychotherapy. HAT theory combines biophysics and cardiovascular psychophysiology with cognitive and affective neuroscience. The inventor of HAT, Dr. John Diepold, approached Dr. Schwartz because of his long-standing research background in cardiovascular psychophysiology, biophysics, and energy medicine.  Dr. Schwartz’s doctoral dissertation from Harvard University was published in the journal Science in 1971 titled “Human cardiovascular integration and differentiation through feedback and reward.”  At the University of Arizona, Dr. Schwartz directed a four-year, NIH-funded Center for Frontier Medicine in Biofield Science, summarized for the public in his 2007 book The Energy Healing Experiments that includes a Foreword by Dr. Richard Carmona, the 47th Surgeon General of the United States.   

Dr. Schwartz has assisted Dr. Diepold in documenting the clinical effectiveness of HAT in the real-world practice of HAT.  The abstract below is currently being considered for publication by a peer reviewed scientific journal.



Context: The need for more effective interventions in healing from traumatic experiences is ongoing. “Healing” from traumatic experiences and “coping” with trauma-related symptoms are conceptionally separate. Objective: This paper describes a specific integrative therapeutic model and reports Phase I pre and post treatment findings of perceived traumatic distress. Setting: All treatment was conducted in individual sessions by two separate psychologists, from 2 different states. Patients: Forty-three patients were treated.  Design: All patients in exploratory and confirmatory groups rated their degree of perceived distress before and after treatment for each distressing and traumatic life event. Additionally, ratings of current and prior therapies and therapist characteristics were obtained. Follow-up data was also collected ranging from 3 months to over 18 months post-treatment. Intervention:  Heart Assisted Therapy (HAT) was used to treat all distressing and traumatic life events. Main Outcome Measure: Pre and post Subjective Units of Distress (0-10 Li). Results: There was a total 81 distressing and traumatic life events treated. The average number of HAT sessions for a treated incident was 3 - 4.  The mean distress level was 7.55 before HAT and 0.00 after HAT for the exploratory study (p<.0000001) and 8.31 before HAT and 0.02 after HAT for the confirmatory study (p<.0000001).   These striking clinical improvements are supported by controlled laboratory EKG and EEG research documenting increased heart-brain connectivity with overlapping hands placed over the heart.


Research is being expanded to measure biophoton emissions from the heart during HAT and related cardiac and mindfulness energy healing modalities.   Dr. Schwartz wrote the Foreword for Dr. Diepold’s 2018 book Heart Assisted Therapy: Integrating Heart Energy to Facilitate Emotional Health, Healing and Performance Enhancement.
