Single-lead ECG tracings along with heart rate and 3-axis chest actigraphy using a Polar H10 sensor worn with on a Polar Pro chest strap, with data transferred via bluetooth to an Android smartphone (Realme 6i) that serves as a bluetooth receptor unit and data recorder via the Polar Sensor Logger app on Android by Jukka Happonen (Polar developer, this app is unofficial): https://play.google.com/store/apps/details?id=com.j_ware.polarsensorlogger Data was compressed with 7-zip using LZMA2 in Normal compression setting and split into 5GB parts to respect the file size limit of figshare. Total is 15.7 GB compressed, 103 GB uncompressed. This dataset covers the period from 2020-10-21 to 2021-03-24. This wearable was only worn when at home. Each file represents one acquisition session, of variable time up to 140h in one session. The acquisition software also split files when the device is temporarily out of reach, so there several files with very few entries, which means the device was barely reachable or went in and out of bluetooth range. These files can be concatenated to study a longer time period. There are 4 types of files: ECG for the raw ECG, HR for the heart-rate computed by the proprietary Polar embedded software in the H10 sensor and also the IBI (inter-beats intervals) to ease calculation of HRV (heart rate variability), ACC for the 3-axis (accelerometer = translation axes) chest actigraphy, and Marker which are manual markers by the operator to mark special temporal events but they were not used for this study so they are either deleted or empty. More data will be added over time.

本数据集包含单导联心电（ECG，Electrocardiogram）波形数据，以及搭载于Polar Pro胸带的Polar H10传感器采集的心率与三轴胸壁活动记录仪数据；数据通过蓝牙传输至作为蓝牙接收与记录终端的Android智能手机（Realme 6i），记录依托Jukka Happonen（Polar开发者）开发的非官方Android应用Polar Sensor Logger实现，该应用下载地址为：https://play.google.com/store/apps/details?id=com.j_ware.polarsensorlogger。
数据采用7-Zip以LZMA2算法并以标准压缩模式进行压缩，并按5GB为单位分卷以适配Figshare的文件大小限制；压缩后总容量为15.7GB，解压后总容量为103GB。
本数据集覆盖的采集时段为2020年10月21日至2021年3月24日，且仅在受试者居家时佩戴采集设备。
每个文件对应一次采集会话，单次会话时长可变，最长可达140小时。当设备临时超出蓝牙覆盖范围时，采集软件会自动拆分文件，因此存在少量条目极少的文件，对应设备几乎无法被检测或频繁进出蓝牙覆盖范围的场景；此类文件可通过拼接以分析更长时段的数据。
本数据集包含4类文件：
1. ECG类：原始心电波形数据；
2. HR类：由Polar H10传感器内置专有软件计算得到的心率数据，同时包含心搏间期（IBI，Inter-Beats Intervals）数据以方便心率变异性（HRV，Heart Rate Variability）的计算；
3. ACC类：三轴胸壁活动记录仪数据（即平移轴加速度计数据）；
4. Marker类：由操作者手动标记的特殊时间事件标记，但本研究未使用此类数据，因此该类文件要么已被删除，要么为空。
后续将持续追加更多数据。
