长期 ST 数据库是多国研究努力的成果。目标是开发一个具有挑战性和现实性的研究资源，用于开发和评估自动化系统，以检测心电图的短暂性 ST 段变化，并支持短暂性心肌缺血机制和动力学的基础研究。根据缺血性和非缺血性 ST 段变化的发生情况，从 1994 年至 2000 年间美国和欧洲的常规临床实践中选择了 24 小时动态心电图记录。人类专家注释者使用新开发的注释协议和专门开发的交互式图形编辑器工具（SEMIA），支持无纸化注释编辑并通过互联网促进国际合作。该数据库包含 80 名患者的 86 条两通道和三通道 24 小时带注释的动态记录，并存储在 DVD-ROM 上。数据库注释文件包含短暂性缺血 (1155) 和心率相关 ST 发作的 ST 段注释以及与姿势变化和传导异常相关的非缺血性 ST 段事件的注释。该数据库旨在补充欧洲心脏病学会 ST-T 数据库以及 MIT-BIH 和 AHA 心律失常数据库。它提供了“真实世界”数据的全面表示，包括短暂性缺血和非缺血性 ST 段变化、心律失常、传导异常、轴移位、噪声和伪影的大量示例。
The long-term ST database is the result of a multinational research effort. The goal was to develop a challenging and realistic research resource for development and evaluation of automated systems to detect transient ST segment changes in electrocardiograms and for supporting basic research into the mechanisms and dynamics of transient myocardial ischaemia. Twenty-four hour ambulatory ECG records were selected from routine clinical practice settings in the USA and Europe, between 1994 and 2000, on the basis of occurrence of ischaemic and nonischaemic ST segment changes. Human expert annotators used newly developed annotation protocols and a specially developed interactive graphic editor tool (SEMIA) that supported paperless editing of annotations and facilitated international co-operation via the Internet. The database contains 86 two- and three-channel 24 h annotated ambulatory records from 80 patients and is stored on DVD-ROMs. The database annotation files contain ST segment annotations of transient ischaemic (1155) and heart-rate related ST episodes and annotations of non-ischaemic ST segment events related to postural changes and conduction abnormalities. The database is intended to complement the European Society of Cardiology ST-T database and the MIT-BIH and AHA arrhythmia databases. It provides a comprehensive representation of 'real-world' data, with numerous examples of transient ischaemic and non-ischaemic ST segment changes, arrhythmias, conduction abnormalities, axis shifts, noise and artifacts.
