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 16.9 GB compressed, 91.1 GB uncompressed. This dataset covers the period from 2022-03-17 to 2022-06-16. There is no overlap with previous sets, this is the continuation. See other sets for further data. This wearable was worn at all time under all conditions. 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.

本数据集包含采用佩戴于Polar Pro胸带上的Polar H10传感器采集的单导联心电图（Single-lead ECG）轨迹、心率数据，以及三轴胸部活动记录仪（3-axis chest actigraphy）数据。数据通过蓝牙传输至作为蓝牙接收单元与数据记录终端的安卓智能手机（Realme 6i），数据记录由Jukka Happonen（Polar公司开发人员，此应用为非官方版本）开发的安卓端Polar Sensor Logger应用完成，应用下载链接：https://play.google.com/store/apps/details?id=com.j_ware.polarsensorlogger。数据集采用7-Zip以LZMA2算法并设置正常压缩模式进行压缩，并分割为单卷最大5GB的分卷以适配figshare平台的文件大小限制，压缩后总容量为16.9 GB，未压缩总容量达91.1 GB。本数据集覆盖2022年3月17日至2022年6月16日的时段，与此前发布的数据集无重叠内容，为其后续补充数据集，更多数据可参阅其他数据集文件。该可穿戴设备在所有场景与时段均持续佩戴。每个文件对应一次采集会话，单一会话时长可变，最长可达140小时。当设备暂时超出蓝牙通信范围时，采集软件会自动分割文件，因此存在少量条目极少的文件，对应设备几乎无法被蓝牙连接或频繁进出蓝牙覆盖范围的场景。此类文件可通过拼接操作以开展更长时段的研究分析。本数据集包含4类文件：1. 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数据，同时附带IBI（心搏间期，inter-beats intervals）以简化HRV（心率变异性，heart rate variability）的计算流程；3. ACC文件：采样率为100Hz、采样分辨率为4g的三轴胸部活动记录仪数据（三轴指加速度计（accelerometer）采集的平移轴数据）；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，因此该类文件要么已被删除，要么为空内容。如需了解Polar H10设备的完整技术规格，请参阅：https://github.com/polarofficial/polar-ble-sdk/tree/master/technical_documentation
