Method and device for predicting blood pressure based on synchronized signals

Abstract

The embodiment of the invention relates to a method and device for predicting blood pressure based on synchronized signals. The method comprises the steps of acquiring PPG signal data and ECG signal data synchronized therewith; carrying out signal sampling processing on the PPG signal data and the ECG signal data separately according to a data sampling frequency threshold to generate a PPG one-dimensional data sequence and an ECG one-dimensional data sequence; carrying out blood pressure CNN input data fusion processing on the PPG one-dimensional data sequence and the ECG one-dimensional datasequence to generate an input data four-dimensional tensor; carrying out multilayer convolution pooling calculation by using a blood pressure CNN model according to a convolution layer number threshold to generate a feature data four-dimensional tensor; constructing a blood pressure ANN input data two-dimensional matrix; carrying out feature data regression calculation by using a blood pressure ANN model to generate a blood pressure regression data two-dimensional matrix; acquiring a prediction mode identifier; generating a mean blood pressure prediction data pair when the prediction mode identifier is mean prediction; and generating a dynamic blood pressure prediction one-dimensional data sequence when the prediction mode identifier is dynamic prediction.

Description

technical field [0001] The present invention relates to the technical field of electrophysiological signal processing, in particular to a method and device for blood pressure prediction based on a synchronization signal. Background technique [0002] The heart is the center of human blood circulation. The heart generates blood pressure through regular pulsation, and then supplies blood to the whole body to complete the metabolism of the human body. Blood pressure is one of the very important physiological signals of the human body. Human blood pressure contains two important values: systolic blood pressure and diastolic blood pressure. Medically, these two quantities are used to judge whether the human blood pressure is normal or not. Long-term continuous observation of these two parameters of blood pressure can help people have a clearer understanding of their own heart health. However, most of the traditional blood pressure measurement methods currently use external press...

Problems solved by technology

However, most of the current traditional blood pressure measurement methods use external pressure detection methods such as manometers, which are not only cumbersome to operate, but also easily cause discomfort to the subjects, so they cannot be used multiple times to achieve the purpose of continuous monitoring
