Clinical HRV and Biofeedback Research

HRV biofeedback, also known as HRV coherence biofeedback, uses real-time monitoring of heart rate variability to help individuals learn to regulate their autonomic nervous system, typically through paced heart-focus breathing exercises and the self-generation of renewing attitudes and emotions.

Clinical studies in this category examine HRV biofeedback in relation to stress, anxiety, depression, PTSD, cardiovascular function, chronic pain, and rehabilitation. Effectiveness varies by condition, population, and study design.

This category features clinical and health-related studies published in peer-reviewed journals, examining HRV biofeedback and or self-regulation training alongside outcomes such as stress, anxiety, cardiovascular function, and other well-being outcome measures. Study designs range from randomized controlled trials to smaller pilot studies.

A randomized controlled trial (RCT) assigns participants to intervention and comparison groups to isolate the effect of the intervention, providing stronger evidence than a case report, which describes outcomes for a single patient or small group without a control comparison.

Safety and adverse-event reporting is required by the most review boards that approve research studies. HRV biofeedback is generally considered a low-risk, non-invasive approach in the published literature, and no adverse events have been reported that we are aware of.
