Clinical research status and application progress of heart rate variability / 中国综合临床

ABSTRACT

Heart rate variability is one of the methods to evaluate cardiac autonomic nervous function. It is widely used because of its non-invasive, convenient, fast and other advantages. Various heart diseases, including cardiovascular disease, arrhythmia and myocardial disease, are closely related to autonomic dysfunction, so heart rate variability has also become one of the important indicators to predict the prognosis of heart disease. This article reviews the research status of heart rate variability and its application in heart disease.
