Method for dynamically monitoring blood pressure based on multiple physiological characteristic parameters of ECG and PPG

Abstract

The invention discloses a method for dynamically monitoring blood pressure based on multiple physiological characteristic parameters of ECG and PPG. The method comprises the following steps: receiving an ECG signal and a PPG signal which are synchronously acquired, and respectively carrying out noise reduction treatment; the preprocessed ECG signals and the preprocessed PPG signals are fused, and a plurality of physiological feature parameters of the fused signals are extracted in a window moving mode; inputting a plurality of groups of physiological characteristic parameters into a blood pressure estimation neural network analysis model for analysis, and adjusting and correcting arbitration weights of neural network elements and blood pressure estimation model coefficients according to blood pressure data model rules to obtain a public blood pressure data measurement model; and inputting an individual determined blood pressure value to correct and compensate the blood pressure data relationship of the public model to obtain an independent individual accurate blood pressure data measurement model. By means of the blood pressure data measurement model of various physiological signal characteristic parameters and the individual factor correction and compensation algorithm and method, the blood pressure measurement precision is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a blood pressure dynamic monitoring method and algorithm based on ECG and PPG multiple physiological characteristic parameters. Background technique [0002] Blood pressure is an important physiological parameter for the diagnosis of cardiovascular diseases. It is of great significance to know the status of blood pressure at all times for patients with cardiovascular diseases. Continuous dynamic monitoring of blood pressure is the most effective means of preventing, diagnosing, treating and controlling hypertension. important risk factors. [0003] At present, there are two types of non-invasive blood pressure measurement methods on the market, one is the traditional measurement method dominated by auscultation, oscillometric method, arterial tension method, etc. These traditional measurement methods have various defects that are not conducive to practical use. For exa...
