Objective: To study the relationship between the heart rate variability (HRV) and autonomic neuropathy in patients with type 2 diabetes (T2DM).
Methods: 50 cases of type 2 diabetes were divided into two groups:the group in which the course of diease was more than 10 years(groupI) were 27 cases, the other group in which the course of diease was less than 10 years(groupII) were 23 cases. The healthy control group(groupIII) were 25 cases. Determin HRV indices of each case,contrast and analyze that in the three groups.
Results: The HRV depress incidence in the three groups were 62.96% 8.70% and 0.00% respectively The distinction was significant.The distinction of SDNN SDANN Index and SDNN Index.in the three groups were significant respectively The distinction of rMSSD PNN50 in : the group I. and III was significant. The distinction of rMSSD PNN50 in :the group II. and III was not significant Conclusion HRV was the earier index to assess the autonomic neuropathy in T2DM.The tension of adrenergic nerve in T2DM was manifest higher,as the course of the disease lasting,the vagus nerve function was being demaged in different degrees.
