摘　　要：目的探讨急性冠脉综合征(ACS)患者心率振荡(HRT)的变化及其临床意义。方法将100例冠心病患者分为2组:ACS组60例和稳定性心绞痛(SAP)组40例,另选同期30例冠状动脉造影正常者为对照组。采用24 h动态心电系统获得其室性早搏,分别计算3组振荡初始(TO)和振荡斜率(TS)2个指标。结果 ACS组TO明显高于SAP组和对照组(P<0.01),而TS则显著低于SAP组和对照组(P<0.01)。结论 ACS患者存在异常的HRT现象,猝死风险较高。Objective To investigate the variation and clinical significance of heart rate turbulence（HRT） in patients with acute coronary syndrome（ACS）.Methods 100 Coronary heart disease patients were divided respectively as the ACS group（60 cases） and the stable angina group（SAP,40 cases）,Meanwhile,screening patients with normal coronary arteriography as the control group（30 cases）.24 h dynamic ecg system was performed in 3 groups for the analysis of TO（Turbulence Onset） and TS（Turbulence Slope）.Results The value of TO was significantly higher in the ACS group than those of the SAP group and control group.but,The value of TS was significantly lower in the ACS group than those of the SAP group and control group.Conclusions patients with ACS have unnormal HRT and higher-risk sudden cardiac death rate.
