心肌梗死患者窦性心律震荡的检测及其临床意义

THE CLINICAL SIGNIFICANCE OF DETECTING SINUS RHYTHM TURBULENCE TO PATIENTS WITH MYOCARDIAL INFARCTION

目的:探讨心肌梗死(心梗)患者窦性心律震荡检测的临床意义。方法:测定24小时动态心电监测的170例心梗患者和116例正常人室性早搏(室早)后的震荡初始(TO)和震荡斜率(TS)值及平均值,并进行对比分析。结果:心梗患者室早后的TO值明显高于对照组、TS值明显低于对照组(p<0.05和p<0.01),TO和/或TS异常组死亡率明显高于TO和TS均正常组(p<0.001)。结论:心梗后患者窦性心律震荡现象减弱或消失时,其猝死的发生率增高,及时检测心梗患者室早后的TO和TS值,对发生猝死的高危患者的检出、危险度分层以及对其进行干预治疗都有重要的临床意义。

Objective： To explore clincal significance of detecting sinus rhythm turbulence in patients with myocardial infarction （MI） . Methods： The TO and TS after ventricular extrasystotl （VE） was measured in 170 cases with MI and 116 cases of control group with Holter. The contrast between them was analysed. Results： The TO of MI was markedly high, TS was markedly low （p 〈0. 05 and p 〈0. 01 ） , the death rate was higher in abnormal group of TO and TS than that in normal group （p 〈 0. 001 ） . Conclusion： The death rate was high when the sinus rhythm turbulence was weakened and vanished. The TO and TS after VE of patients with MI should be measured in time. It is valueable for the detecting of sudden death, grade of danger levels and intervening treatment.
