Brno University of Technology Smartphone PPG Database (BUT PPG)

Brno University of Technology Smartphone PPG Database (BUT PPG) is a database created by the cardiology team at the Department of Biomedical Engineering, Brno University of Technology, for the purpose of evaluating PPG quality and estimation of heart rate (HR). The data comprises 48 10-second recordings of PPGs and associated ECG signals used for determination of reference HR. The data were collected from 12 subjects (6 female, 6 male) aged between 21 to 61 years. Recordings were carried out between August 2020 and October 2020. PPG data were collected by smartphone Xiaomi Mi9 with sampling frequency of 30 Hz. Reference ECG signals were recorded using a mobile ECG recorder (Bittium Faros 360) with a sampling frequency of 1,000 Hz. Each PPG signal includes annotation of quality and reference HR. PPG signal quality is indicated binary: 1 indicates good quality for HR estimation, 0 indicates signals where HR cannot be detected reliably and thus these signals are unsuitable for any analysis.

布尔诺理工大学智能手机光电容积描记（Photoplethysmography，PPG）数据库（BUT PPG）由布尔诺理工大学生物医学工程系的心脏病学团队构建，旨在用于评估PPG质量与心率（Heart Rate，HR）估算。该数据集包含48段时长为10秒的PPG信号及配套心电图（Electrocardiography，ECG）信号，用于确定参考心率。数据采集自12名受试者（6名女性、6名男性），年龄介于21至61岁之间，采集工作开展于2020年8月至2020年10月期间。PPG信号通过小米Mi9智能手机采集，采样频率为30赫兹；参考ECG信号采用移动心电记录仪（Bittium Faros 360）采集，采样频率为1000赫兹。每一段PPG信号均包含质量标注与参考心率值。PPG信号质量采用二进制标注：1代表可用于心率估算的优质信号，0代表无法可靠检测心率的信号，因此此类信号不适用于任何分析。
