摘要
[目的]探讨窦性心律震荡现象(HRT)对急性心肌梗死预后的影响。[方法]分析2006年1月至2010年5月我院心内科确诊为急性心肌梗死患者120例(急性心肌梗死组)与同期住院存在室性期前收缩的非心肌梗死患者100例(对照组)的24h动态心电图,计算窦性心律震荡的两个量化指标震荡初始(TO)和震荡斜率(TS),并进行组间比较。[结果]急性心肌梗死组与对照组TO、TS比较,急性心肌梗死组TO值高、TS值低,差异有统计学意义(P<0.05);与急性心肌梗死存活组TO、TS比较,死亡组TO值高、TS值低,差异均有统计学意义(P<0.05)。[结论]HRT的减弱或消失可作为急性心肌梗死死亡率的预测指标。
[Objective] To study the effect of sinus heart rhythm shake on acute MI prognosis. [Result] Analyse the 24-h dynamic ECG of 120 such cases (MI group) and other 100 non-MI cases(control group), calculate the 2 quantification indexes of shake initial and slope of sinus heart rhythm shake, and make comparison. [Result] Compared TO and TS of both, MI group had higher TO and lower TS than other group, with statistical meaning of difference. [Conclusion] The reduction or disappearance of sinus heart rhythm can be taken as forecasting index for acute MI mortality.
