摘要
Heart rate variability(HRV)is a non-invasive index used to assess autonomic nervous function in heart,which has been widely used in evaluation of hypertension,coronary heart disease,diabetes and other diseases.Chro-nic heart failure(CHF)induces ventricular remodeling by slowly activating neuroendocrinal system,and HRV grad-ually decreases with the decline of human cardiac function.The present article makes a review on correlation be-tween CHF and Parkinson's disease(PD)and its possible mechanism,as well as the change characteristics of HRV in CHF complicated PD,aiming at providing direction for follow-up development of targeted treatment and preven-tion strategies for PD patients,and it is conducive to improve quality of life of PD patients.
