≪Organizer Abstract≫
Heart rate variability (HRV) is a measure of the spontaneous fluctuations of heart period which reflects autonomic nervous system function. HRV has also attracted growing attention as a biological marker for emotional regulation, whereas HRV biofeedback (HRV-BF), an intervention aimed at increasing HRV, has clinical utility in the treatment of a variety of physical and mental disorders that involve autonomic nervous system dysregulation. First, Dr. Hirota (Japan) presents history of Japanese Society of Biofeedback Research and hot topics in HRV. After this, Dr. Sakakibara (Japan) describes data from psychophysiological studies that address the effectiveness of HRV-BF. Next, Dr. Uratani (Japan) reports data from application of respiration-guiding stuffed toy for relaxation, which shed lights on interdisciplinary collaboration of psychology and engineering for increasing HRV. Finally, Dr. Katsamanis (USA) discusses clinical work addressing the usefulness of HRV-BF in the patients with depression. Potential possibilities of HRV for future work will be discussed.
