Effects of Heart Rate Variability Biofeedback Training on Anxiety Reduction and Brain Activity: a Randomized Active-Controlled Study Using EEG
Heart rate variability biofeedback (HRVBF) is a promising anxiety-reducing intervention that increases vagally-mediated heart rate variability (vmHRV) through slow-paced breathing and feedback of heart rhythm. Several studies have reported the anxiety-reducing effects of HRVBF; however, some studies have reported such training as ineffective. Furthermore, the effects of training and underlying brain activity changes remain unclear. This study examined the anxiety-reducing effects of HRVBF training and related brain activity changes by randomly assigning participants, employing an active control group, and measuring anxiety-related attentional bias using the emotional Stroop task and electroencephalography (EEG). Fifty-five healthy students with anxiety were randomly assigned to the HRVBF or control groups, and 21 in the HRVBF group and 19 in the control group were included in the analysis. Both groups performed 10 training sessions of 20 min each within 3 weeks. They were assessed using resting vmHRV, event-related potential (ERP), time-frequency EEG, attentional bias, and the State-Trait Anxiety Inventory-JYZ (STAI-JYZ) before and after training. The results demonstrated increased resting vmHRV in the HRVBF group compared to the control group after training. However, no differences were observed in ERP, time-frequency EEG, attentional bias, and STAI-JYZ. Participants with higher pre-training resting vmHRV achieved higher heart rhythm coherence in HRVBF training and had reduced attentional bias. This study suggests that individuals with higher resting vmHRV are more likely to be proficient in HRVBF training and benefit from its anxiety-reducing effects. The findings contribute to participant selection to benefit from HRVBF training and modification of the training protocols for non-responders.

期刊介绍：
Applied Psychophysiology and Biofeedback is an international, interdisciplinary journal devoted to study of the interrelationship of physiological systems, cognition, social and environmental parameters, and health. Priority is given to original research, basic and applied, which contributes to the theory, practice, and evaluation of applied psychophysiology and biofeedback. Submissions are also welcomed for consideration in several additional sections that appear in the journal. They consist of conceptual and theoretical articles; evaluative reviews; the Clinical Forum, which includes separate categories for innovative case studies, clinical replication series, extended treatment protocols, and clinical notes and observations; the Discussion Forum, which includes a series of papers centered around a topic of importance to the field; Innovations in Instrumentation; Letters to the Editor, commenting on issues raised in articles previously published in the journal; and select book reviews. Applied Psychophysiology and Biofeedback is the official publication of the Association for Applied Psychophysiology and Biofeedback.
