  Heart rate variability biofeedback (HRVB) refers to a therapy training that helps patients regulate their heart rate variability (variation in the time interval between consecutive normal heartbeats) based on a certain protocol. HRVB stimulates the cardiovascular system with its resonance frequency and enhances autonomic homeostatic function ; respiratory sinus arrhythmia and baroreceptor reflex play important roles in this process. The standard protocol of HRVB consists of regular training sessions about once a week and home practice for 40 minutes (20 minutes×2 times) per day. In the wake of the COVID-19 pandemic, face-to-face intervention in the laboratory and clinic requires sensitive care to prevent the transmission of COVID-19. However, remote HRVB intervention through online devices is fully possible, because biofeedback is by nature a technique for displaying and adjusting physiological responses through information devices. This paper first describes the mechanism and clinical effects of HRVB, and then explores the potential and ethical aspects of remote HRVB. Finally, the implications of future research on HRVB are discussed.
