摘　　要：目的探讨窦性心率震荡现象对慢性心力衰竭患者发生心源性猝死的预测。方法测量和比较152例慢性心力衰竭患者和150例健康人室性期前收缩后的窦性心率震荡初始(TO)与震荡斜率(TS)值。其中心力衰竭组发生心源性猝死者47例。结果随访2±0.5年,发现心力衰竭组T0(0.11%±0.18%)高于健康组(-0.03%±0.13%),TS(2.25±0.60/ms/R-R)低于健康组(3.14±0.85/ms/R-R),差异均有非常统计学意义(P<0.01),其中47例心源性猝死组TO与TS值均心力衰竭组最高,差异均有非常统计学意义(P<0.01)。结论窦性心率震荡现象可作为慢性心力衰竭心源性猝死的预测指标。Objective To investigate clinical significance of heart rate turbulence in patients. Methods with chronic Turbulence onset（TO） and turbulence Slope（TS） were measured and compared between 152 cases with CHF（CHF group）and 100 subjects with ventricular entrasystde（control group）. Result During a follow-up of 2±0.5 years, to was higher and TS was lower in CHF group （0.11%±0.18%, 2.25±0.60/ms/R-R） than that in control group（0.03%±0.13%, 3.14±0.85/ms/R-R）. The dfference between them was significant（both P〈0.01）. 47 cases of them come out SCD, mortality was highest in patients with both abnormal TO and TS. Conclusion HRT may be a predictor of mortality after CHF with SCD.
