T-Wave Alternans Challenge Database

This database has been assembled for the PhysioNet/Computers in Cardiology Challenge 2008. It contains 100 multichannel ECG records sampled at 500 Hz with 16 bit resolution over a ± 32 mV range. The subjects include patients with myocardial infarctions, transient ischemia, ventricular tachyarrhythmias, and other risk factors for sudden cardiac death, as well as healthy controls and synthetic cases with calibrated amounts of T-wave alternans.

本数据库旨在为 2008 年 PhysioNet/Computers in Cardiology Challenge 设计构建。该数据库包含 100 份多通道心电图记录，采样频率为 500 Hz，分辨率达到 16 位，覆盖 ± 32 mV 的电压范围。研究对象包括心肌梗死患者、短暂性缺血患者、心室性心动过速患者以及其他突发性心脏死亡风险因素的患者，还包括健康对照者以及具有校准 T 波交替量的合成病例。
