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 18 GB compressed, 106 GB uncompressed. This dataset covers the period from 2021-10-09 to 2022-01-26, with a few 3-days gaps due to travelling and end of year festivities. There is no overlap with previous sets, this is the continuation. See other sets for further data. 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 at 133Hz sampling rate, 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 set at 100Hz sampling rate and 4g sampling resolution, 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.

ECG文件：采样率为133Hz的原始心电图数据； 2. HR文件：由Polar H10传感器内置专有软件计算得到的心率（HR）数据，同时包含心搏间期（IBI）数据以简化心率变异性（HRV）的计算流程； 3. ACC文件：采样率为100Hz、采样分辨率为4g的三轴加速度计（accelerometer，对应平移轴）胸壁活动记录数据； 4. Marker文件：由操作人员手动标记的特殊时间事件标记，但本研究未使用此类数据，因此该类文件均为空或已被删除。 如需获取Polar H10设备的完整技术规范，请访问：https://github.com/polarofficial/polar-ble-sdk/tree/master/technical_documentation
