摘要
目的:探讨急性心肌梗塞(AMI)时心电图QT间期离散度的改变与心室颤动之间的关系。方法:回顾性分析25例AMI后24小时内发生心室颤动的患者(心室颤动组)和32例未发生心室颤动的AMI患者(对照组),对比分析两组急诊时体表同步12导心电图的QT间期离散度和QTc间期离散度。结果:心室颤动组QTc间期离散度和QT间期离散度均显著高于对照组(分别为76ms±15ms与33ms±16ms和73ms±21ms与40ms±14ms,P<0.001)。结论:AMI时QT间期离散度增加可导致心室颤动的危险性增加。
Objective： To investigate the relationships between increased QT interval dispersion on ECG during AMI. Methods： QT and QTe dispersions of 25 AM1 patients （VF group） with subsequent ventricular fibrillation and 32 AMI patients （control group） without subsequent ventricular fibrillation within 24 hours of hospitalization were analyzed. Results： The mean precordial QTc and QT interval dispersions were 76ms±15ms. 33ms±16ms and 73ms±21 ms. 40ms±14ms. P 〈 0. 001 for VF group and control group, respersions. Conclusions： QT interval dispersion could predict the risk for ventricular fibrillation in the course of AMI.
