目的：评价心率变异性（ＨＲＶ）分析在糖尿病心脏自主神经病变早期诊断中的作用。方法：采用ＨＲＶ分析研究糖尿病患者的心率变异特性。结果：糖尿病患者ＨＲＶ明显低于正常人，且昼夜变化节律消失。结论：ＨＲＶ是一种敏感的糖尿病心脏自主神经病变检测方法。
PURPOSE: To evaluate the role of heart rate variability (HRV) in the early diagnosis of diabetic autonomic neuropathy. Methods: HRV analysis of heart rate variability in patients with diabetes. Results: HRV in diabetic patients was significantly lower than that in normal people, and circadian rhythms disappeared. Conclusion: HRV is a sensitive method to detect diabetic autonomic neuropathy.
