CACHET-CADB

CACHET-CADB is 259 days long contextualised single-channel ECG arrhythmia database from 24 patients recording under a free-living ambulatory setting. Along with the ECG, it also contains contextual information such as activities, body position, movement acceleration, patients reported unusual symptoms/events diary, step counts, patient-reported sleep quality, stress level, and food intake. I contain 1602 ten-second long ECG samples of AF, NSR, noise, and other rhythm classes, which are manually annotated by two cardiologists. The ECG is sampled at 1024 Hz and a 12-bit resolution.<br>There is a short format of the dataset available at 10.11583/DTU.14547330<br> <br>Further details and code for using the database can be found on the GitHub repository https://github.com/cph-cachet/cachet-ecg-db.CACHET-CADB是时长259天的单通道心电图（Electrocardiogram, ECG）心律失常数据库，其数据源自24名患者在自由生活状态下的动态监护场景下的记录。该数据集除包含心电图数据外，还涵盖各类上下文关联信息，具体包括活动状态、身体姿势、运动加速度、患者自行填报的异常症状/事件日志、每日步数、患者自评睡眠质量、压力水平以及饮食摄入情况。该数据集共包含1602段时长10秒的心电图样本，涵盖心房颤动（Atrial Fibrillation, AF）、正常窦性心律（Normal Sinus Rhythm, NSR）、噪声及其他节律类型，所有样本均由两名心脏科医师手动标注。该心电图数据的采样率为1024 Hz，分辨率为12位。<br>该数据集的精简版本可通过DOI：10.11583/DTU.14547330获取。<br>有关该数据库的更多详细信息及使用代码，可访问其GitHub仓库：https://github.com/cph-cachet/cachet-ecg-db。
