许多临床研究证实，急性心肌梗死（AMI）患者QT间期离散度（QTd）及JT间期离散度（JTd）增加与心律失常及摔死的发生密切相关。但QTd及JTd增大与AMI部位和范围的关系尚不十分明确。本文结合96例AMI病例就此作初步探讨。1资料与方法1．1研究对象AMI组：选择1995年1月～1998年1月
Many clinical studies have confirmed that patients with acute myocardial infarction (AMI) QTd dispersion (JTd) and JTd increase (JTd) is closely related to arrhythmia and the occurrence of death. However, the relationship between the increase of QTd and JTd and the location and range of AMI is not yet clear. In this paper, 96 cases of AMI cases for this preliminary study. 1 Materials and Methods 1.1 Study AMI group: choose January 1995 to January 1998
