摘　　要：心电图中的QT间期主要反映了心室复极化的时程,而QT间期的变异蕴含了心室复极变化的重要信息,对这些信息的提取和分析对研究心肌缺血、恶性心律失常等疾病有重要的意义。文中针对QT间期自动检测算法、QT离散度分析和QT变异性分析,分别介绍了它们的研究方法和研究进展,并指出了今后的发展方向。The electrocardiographic QT intervals mainly represent the duration of ventricular repolarization, and changes in QT intervals provide valuable information of ventricular repolarization. Extraction and analysis of these information are of great significance in the study of cardiovascular disease such as myocardial isehemia, malignant arrhythmia and so on. This paper introduced the major progress in automatic algorithms for QT interval detection, and the analysis methods for QT dispersion and QT variability. The directions for future study were also discussed.
