Pulse wave database

The database includes 477 subjects (54% male, 46% female). Data were collected from three hospitals: the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine, Liuyang Hospital of Traditional Chinese Medicine, and the Affiliated Hospital of Hunan University of Traditional Chinese Medicine, between 2016 and 2017, from individuals undergoing physical examinations. The data primarily consisted of pulse waveform signals, age, gender, systolic blood pressure, diastolic blood pressure, and BMI. This study utilized a pulse data acquisition device developed by the Chinese Academy of Medical Sciences (CACMS) (Patent No. 200810225717.0), which employs pressure sensors. The device is capable of simultaneously collecting pulse data from three channels on a single wrist at a sampling frequency of 1000 Hz. Additionally, the device automatically saves the data collected by the sensors to the local disk. Prior to testing, all participants rested for at least 3 minutes. Pulse data from six channels were then sequentially recorded, with each recording lasting approximately 30 seconds. During the test, participants were instructed to sit upright with their arms relaxed, ensuring that the core and position remained nearly level throughout the data collection process. The device also allows for adjustment of the contact pressure on the skin to obtain clear pulse data. For the purposes of this database, only the pulse data from a single channel was selected.<br>本数据库共纳入477名受试者，其中男性占比54%，女性占比46%。 数据采集于2016年至2017年间，采集地点为三家医院：湖南中医药大学第一附属医院、浏阳市中医医院及湖南中医药大学附属医院，采集对象为接受体检的个体。 本次研究所获数据主要包含脉搏波形信号、年龄、性别、收缩压、舒张压以及身体质量指数（BMI）。 本研究使用了由中国医学科学院（Chinese Academy of Medical Sciences, CACMS）研发的脉搏数据采集设备，其专利号为200810225717.0，该设备采用压力传感器，可在单腕部同时采集三路脉搏数据，采样频率达1000 Hz。此外，该设备可自动将传感器采集的数据保存至本地磁盘。 测试前，所有受试者需静息至少3分钟。随后依次记录六路脉搏数据，单次记录时长约30秒。测试过程中，要求受试者保持端坐姿势、手臂放松，确保数据采集全程躯干与采集部位基本保持水平。该设备还可调整与皮肤的接触压力，以获取清晰的脉搏信号。 本数据库仅选用单通道的脉搏数据。
