| 摘 要： | 目的探讨高龄(≥70岁)冠心病患者心率变异性(HRV)的变化。方法对高龄冠心病组(300例)与正常对照组(198例)的电信号进行研究,观察比较时域指标:连续24 h内正常RR间期的标准差(SDNN)、全程记录中每5分钟正常RR间期平均值的标准差(SDANN)、相邻正常RR间期差值的均方根(RMSSD)、相邻RR间期差值>50 ms百分比(PNN50);频域指标:总功率(TP)、低频功率(LF)、高频功率(HF)。结果冠心病组HRV的SDNN、SDANN、RMSSD、PNN50、HF显著低于正常对照组(P<0.01),TP、LF比较差异无统计学意义(P>0.05)。结论高龄冠心病患者存在自主神经功能紊乱,迷走神经活性降低,交感神经活动相对增强。 |

| Abstract: | Objective To explore the diversity of heart rate variability(HRV)in eldeer patients(≥70years)with coronary heart disease.Methods Electrical signals of elder patients with coronary heart disease(n=300)and control group(n=198)were studied.Time domain index including SDNN,RMANN,PNN50,and frequency domain index including TP,LF,HF were observed.Results SDNN,SDANN,PNN50,HF of patients with coronary heart disease were lower than those of normal group significantly(P<0.01).TP,LF difference had no statistical significance(P>0.05).Conclusion Function disorder of autonomic nerve developed in elder patients with coronary heart disease,the activity of nerve vagus attenuates,the activity of sympathetic nervous accentuates relatively. |
