U.S., Nov. 3 -- ClinicalTrials.gov registry received information related to the study (NCT07911215) titled 'Effects of Brief Heart Rate Variability Biofeedback on Physiological and Emotional Responses' on Oct. 26.

Brief Summary: This completed randomized laboratory study investigated the immediate effects of a single 10-minute session of heart rate variability biofeedback (HRV-B) on cardiac activity, forehead physiological signals, and emotional responses in adults.

Heart rate variability reflects changes in the time intervals between heartbeats. HRV biofeedback provides real-time information about heart rhythm patterns and allows individuals to adjust their breathing in response to visual feedback.

Thirty-two adult participants were ran...
