体表心电图上Q-T间期反映了相应局部心肌的激动和复极过程,Q-T间期离散度(QTd)反映局部心肌的激动和复极不同步性和电不稳定性,与恶性心律失常和心源性猝死的发生密切相关[1,2]。本文旨在探讨急性心肌梗死(AMI)患者行PCI术前后Q-T间期离散度的影响,现报告如下。1对象和方法1·1
The QT interval on the body surface electrocardiogram reflects the activation and repolarization of the corresponding local myocardium. The QTd reflects the agitation and repolarization discomfort of local myocardium and electrical instability, and the relationship between malignant arrhythmia and heart failure The incidence of sudden death is closely related to [1,2]. This article aims to investigate the acute myocardial infarction (AMI) patients before and after PCI Q-T interval dispersion, the report is as follows. 1 objects and methods 1.1
