摘　　要：目的:研究冠状动脉粥样硬化性心脏病(冠心病)患者心率变异性(HRV)和Q-Tc离散度的临床特点。方法:入选78例确诊的冠心病患者为冠心病组,入选64例冠状动脉造影正常的为对照组,所有研究对象均进行24 h动态心电图监测,对两组的心率变异性和Q-Tc离散度指标进行统计学分析。结果:冠心病组的心率变异性指标SDNN、RMSSD、pNN50、SDANN较对照组明显降低,Q-Tc离散度较对照组明显延长,差异具有统计学意义(P<0.05)。结论:冠心病患者心率变异性明显降低,Q-Tc离散度明显延长。Objective：To reseach the clinical character of the heart rate variability（HRV） and QT dispersion in the patients with coronary heart disease（CHD）.Method：The patients with coronary heart disease by coronary angiography confirmed（CHD group,n=78） and normal coronary angiography examiners（control group,n=64） were chosen and given 24 h dynamic electrocardiogram monitoring.The parameters of HRV and QT dispersion were calculated, and the features of these parameters were compared and analyzed between the two groups.Result：HRV（SDNN,SDANN,RMSSD,pNN50,TP and HF）decreased in CHD group compared with control group（P0.05）,while QT dispersion prolonged in CHD group compared with control group（P0.01）.Conclusion：HRV is decreased and QT dispersion is prolonged in CHD patients.
