Abstract Heart rate variability (HRV) is one of the most commonly used non-invasive methods for evaluating cardiac autonomic nerve activity. The decrease of HRV is an independent risk factor for predicting the death of patients with coronary heart disease, and it is also clinically valuable in evaluating essential hypertension, diabetes,
sleep apnea syndrome, depression, corona virus disease 2019 and other diseases. This paper systematically describes the research background, regulatory mechanism, analytical methods and research progress in clinical application of HRV, and puts forward the research direction in the future.
