摘要
目的:探讨急性心肌梗死患者QT间期离散度与恶性室性心律失常发生率的关系。方法:观察64例AMI患者发病24小时内的QT离散度,并观察其与两周内恶性心律失常发生率的关系。结果:急性心肌梗死组QT离散度较对照组增大;发生恶性心律失常的患者QT离散度与未发生者有显著统计学差异。结论:急性心肌梗死患者QT离散度增大对恶性心律失常的发生有预测性。
Objective： to investigate the relationship between QT dispersion in patients with acute myocardial infarction. Methods. the QT dispersion of 64 eases with aeute myocardial infarction were measured, while the ralationship between QTd and the ineidence of malignant ventrieular arrhythmia within two weeks were discussed. Result.. the QTd of patients with AMI were apparently higher than QTd of the control groups, and it was found that there was obviously differences between patients with malignant ventricular arrhythmia and those without. Conclusion. QTd is of value to predicting the malignant ventrieular arrhythmia？ s happening in acute myocardial infarction.
