糖尿病与冠心病患者心率变异性分析

目的 探讨糖尿病与冠心病患者心率变异（ＨＲＶ）改变及其异同，并观测疾病状态下ＨＲＶ改变的昼夜节律性。方法 观察２５例糖尿病患者、２例冠心病患者及４８名健康人２４ｈ、白天段及夜间段心率变异长程时域。结果 糖尿病组与冠心病组ＨＲＶ各指标ＳＤＮＮ、ＲＭＳＳＤ、ＰＮＮ５０、ＳＤＡＮＮ均显著低于健康对照组（Ｐ〈０．０１）。糖尿病组与冠心病组及２组内白天与夜间ＨＲＶ各指标比较均无显著性差异。结论 糖尿病、冠心

Analysis and comparison of heart rate variability in patients with diabetes mellitus and patients with coronary heart disease

Objective To investigate the alteration of heart rate variability (HRV) in patients with diabetes mellitus (DM) and patients with coronary heart disease (CHD) and the difference of HRV between the two groups. Method HRV time domain of 25 DM patients,22 CHD patients and 48 healthy aduts as control in 24 hours, daytime and nighttime were determined and analyzed.Results The SDNN, RMSSD, PNN50, SDANN in two groups of patients were lower than those in control group. These parameters had no significant difference between DM group and CHD group. ALL HRV parameters between daytime and nighttime had no difference.Conclusion HRV in DM patients and CHD patients decreased significantly, HRV analysis was perhaps devoid of specification,and the DM patients and CHD patients lost circadian rhythm of autonomic function.
