摘　　要：目的:探讨急性心肌梗死(AMI)患者窦性心率震荡(HRT)的变化及其对死亡的预测价值。方法:入选AMI患者48例(AMI组)与健康体检者40例(正常对照组)。AMI组根据随访2年结果又分为存活组37例与死亡组11例,对所有研究对象的HRT两项常用指标震荡初始(TO)和震荡斜率(TS)进行比较分析。结果:与正常对照组比较,AMI患者中TO明显升高[(-2.89±2.71)%比(0.21±3.56)%],TS明显降低[(12.28±5.02)ms/R-R比(4.12±6.38)ms/R-R],P均<0.01。与AMI存活组比较,死亡组TO显著升高[(0.18±4.77)%比(2.24±4.31)%],TS显著降低[(6.81±2.02)ms/R-R比(3.58±3.72)ms/R-R],P均<0.05。结论:急性心肌梗死患者窦性心率震荡明显异常,窦性心率震荡异常可作为心肌梗死后猝死高危患者可靠的预测方法。Objective：To investigate change of sinus heart rate turbulence（HRT） in patients with acute myocardial infarction（AMI） and its predictive value on death.Methods：Retrospective analysis was performed in 48 AMI patients（AMI group） and 40 healthy subjects（normal control group）.According to results of two-year follow up,AMI group was divided into survival group（n=37） and dead group（n=11）.Two indexes of HRT [turbulence onset（TO） and turbulence slope（TS）] were measured in all subjects for comparison and analysis.Results：Compared with normal control group,TO [（-2.89±2.71）% vs.（0.21±3.56）%] significantly increased and TS [（12.28±5.02）ms/R-R vs.（4.12±6.38） ms/R-R] significantly decreased in AMI group,P〈0.01 both.Compared with AMI survival group,TO [（0.18±4.77） ]% vs.（2.24±4.31））%] significantly increased and TS [（6.81±2.02） ms/R-R vs.（3.58±3.72） ms/R-R] significantly decreased in dead group,P〈0.05 both.Conclusion：Sinus heart rate turbulence is remarkably abnormal in patients with acute myocardial infarction,and abnormal sinus heart rate turbulence could be a reliable predictive method for patients with high risk of sudden death after myocardial infarction.
