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>
