Research Progress in Heart Rate Variability Applications in Exercise Rehabilitation for Cardiovascular Diseases

Abstract

Heart rate variability (HRV) is an important marker for assessing the balance of the autonomic nervous system and clinical prognosis, because it can be non-invasively and easily measured, and the results are accurate and valuable. HRV is widely applied in cardiovascular disease fields. Exercise training is an important part of cardiac rehabilitation. Personalized sports rehabilitation therapy can effectively prevent the emergence of cardiovascular diseases, decrease the risk of recurrent cardiovascular events, and ameliorate dysfunction, as well as limitations in life, work, and social participation, caused by adverse cardiovascular events. However, sports rehabilitation can have drawbacks, in that improper training can cause injury, excessive fatigue, or even harmful cardiovascular events. To support future applications, this article reviews recent applications of HRV in sports rehabilitation for cardiovascular diseases.
