对６３例Ⅱ型糖尿病（ＮＩＤＤＭ）患者血糖控制前后心率变异性（ＨＲＶ）进行了观察。结果表明，ＮＩＤＤＭ患者ＨＲＶ明显降低，提示存在心脏自主神经病变。老年ＮＩＤＤＭ患者交感神经与迷走神经均有严重损害。非老年ＮＩＤＤＭ患者血糖控制后ＨＲＶ显著改善，提示其自主神经病变具有一定的可逆性；老年ＮＩＤＤＭ患者血糖控制后ＨＲＶ恢复不明显，提示其自主神经病变可逆性差。
The heart rate variability (HRV) of 63 patients with type 2 diabetes mellitus (NIDDM) before and after the control of blood glucose was observed. The results showed that HRD was significantly lower in patients with NIDDM, suggesting the presence of autonomic neuropathy. Elderly patients with NIDDM sympathetic and vagal have serious damage. The non-elderly patients with NIDDM after the blood glucose control significantly improved HRV, suggesting that its autonomic neuropathy has a certain reversibility; elderly patients with NIDDM after blood glucose control HRV recovery was not obvious, suggesting that its reversibility of autonomic neuropathy is poor.
