Abstract: A method for calibrating a blood pressure measurement device includes obtaining first blood pressure measurement information and a current confidence coefficient corresponding to the first blood pressure measurement information, determining the first blood pressure measurement information as blood pressure calibration information in response to the blood pressure measurement device comprising the historical calibration parameter list, and the current confidence coefficient being greater than or equal to a preset confidence coefficient or the historical confidence coefficient, and updating the historical calibration parameter list based on the first blood pressure measurement information and the current confidence coefficient.

Abstract: A method includes obtaining a filtered waveform signal, marking the waveform signal as K signal line segments based on monotonicity, extracting line segment data of each signal line segment, and determining a line segment matching template of the waveform signal based on the line segment data of each signal line segment, where the line segment matching template includes M consecutive signal line segments, and M is an integer less than K. The method further includes matching each of the K signal line segments with the M signal line segments included in the line segment matching template, and determining a target wave group of the waveform signal based on a matching result of each signal line segment. The method further includes determining periodic signal data of the waveform signal based on line segment data of the target wave group.

Abstract: Blood pressure detection signal sampling and compensation methods and apparatuses, and an example blood pressure signal collection system are described. One example method described includes controlling an electrocardiogram (ECG) sampling module and a photoplethysmogram (PPG) sampling module to simultaneously sample a standard periodic signal. Sampling frequencies and sampling end times are separately obtained. A sampling start time and a sampling frequency of the ECG sampling module or the PPG module is then compensated so that a sampling frequency deviation is less than a preset frequency threshold and a sampling end time difference is less than a preset time threshold.

Abstract: An electrocardiogram waveform signal method includes obtaining a filtered waveform signal, marking the waveform signal as K signal line segments based on monotonicity, extracting line segment data of each signal line segment, and determining a line segment matching template of the waveform signal based on the line segment data of each signal line segment. The extracting of the line segment includes extracting a line segment length Xi and a line segment width Yi of each signal line segment i of the K signal line segments, performing difference extension on the line segment length Xi and the line segment width Yi based on a preset length and a preset width, respectively, to obtain a normalized signal line segment j, and extracting fourth line segment data of the normalized signal line segment j.
