摘　　要：目的回顾性分析窦性心率震荡现象对急性心肌梗死预后的影响。方法观察167例急性心肌梗死患者发病后7～25天的窦性心律震荡初始(TO)与震荡斜率(TS)值,评价TO、TS及其他危险因子对死亡的预测价值。结果随访(22±12.3)月,共死亡18例。Logistic多元回归分析显示急性心肌梗死死亡与窦性心率震荡分类、低左心室射血分数(≤55%)及高龄(≥65岁)显著相关,其危险度相关系数分别为50.708(P<0.01)、11.186(P<0.01)及4.828(P<0.01)。结论窦性心率震荡现象可作为急性心肌梗死死亡率的预测指标。Objective TO analyze the effect of heart rate turbulence（HRT） on prognosis of acute myocardial infarction. Methods Turbulence onset, turbulence slope and other parameters were measured retrospectively 7 to 25 days after acute myocardial infarction in 167 patients. Results At follow up of 22 ± 12.3 months, 18 patients died. Logistic multivariate analysis showed that HRT category, Jow left ventricular ejection fraction （ ≤55% ） and old age （ ≥65 years ） were significantly related to the death of acute myocardial infarction. The risk correlation coefficients were 50.70.8 （ P〈0.01 ）, 11.186 [ P〈0.01 ） and 4.828 [ P〈0.01 ）, respectively. Conclusion HRT may be a predictor of mortality after acute myocardial infarction.
