摘　　要：目的　评价一般老年冠心病 (CAD)患者心率变异性 (HRV)减低与心血管事件的关系。方法　回顾性分析我院干部查体中有CAD者 2 4h动态心电图 (DCG)HRV资料与心血管事件的关系 ,共 2 38例。HRV分析包括时域分析和频域分析。比较查体者有和无心血管事件组各时域和频域参数有无差别。结果　有 2 7例老年人发生心血管事件 (有心血管事件组 ) ,2 11例未发生心血管事件 (无心血管事件组 ) ,有心血管事件组与无心血管事件组比较 ,HRV各参数均明显降低 (P <0 .0 1)。结论　一般老年CAD患者如HRV明显降低 ,则易于发生心血管事件。Objective To evaluate the relationship between reduced heart rate variability(HRV) and cardiovascular events in the elderly with coronary artery disease (CAD).Methods The relationship between 24 hour dynamic electrocardiographic data from routine annual physical examination and cardiac events in 238 elderly patients with CAD was analyzed retrospectively.HRV data including time domain analysis and frequency domain analysis were analyzed. Results 27 cases developed cardiac events (cardiac event group) and 211 cases did not (non cardiac event group).There were significant differences in HRV parameters between two groups (P<0.01).Conclusions There was strong association between reduced HRV and increased cardiac events in elderly people with CAD.
