Abstract

The invention is applicable to the technical field of computers and provides a blood pressure measurement method and device based on pulse waveforms and electrocardiogram signals. The method comprises the steps that pulse waveforms and electrocardiogram signals are obtained, feature points of the pulse waveforms are extracted, and R wave peaks of the electrocardiogram signals are identified; according to the pulse waveforms, kurtosis coefficients, skewness coefficients and pulse coefficients are calculated, and primary diagnosis results are obtained; signal sampling coordinate differences are calculated, regression detection is conducted on the feature points, and systolic pressure and diastolic pressure are respectively calculated. The feature points of the pulse waveforms, the kurtosis coefficients, the skewness coefficients and the pulse coefficients are obtained by acquiring the pulse waveforms and electrocardiogram signals of a user, signal sampling coordinate differences are calculated, an equation of linear regression is established, the systolic pressure and the diastolic pressure are respectively calculated, the influence of atypical pulse waveforms on follow-up blood pressure measurement is inhibited to the most degree, the shortcoming of inaccurate diastolic pressure measurement of an original method is overcome, and the measurement accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and device for measuring blood pressure based on a pulse wave waveform and an electrocardiogram signal. Background technique [0002] Currently in medicine, blood pressure measurement methods are mainly divided into invasive blood pressure measurement and non-invasive blood pressure measurement. [0003] Invasive blood pressure measurement refers to implanting a pressure sensor into the aorta of the human body in an invasive manner to detect pressure changes during cardiac pacing. The change of the liquid level of the inner liquid column is used to measure the pressure brought by the cardiac pacing inside the catheter, so as to measure the blood pressure value. The measurement result of this method is very accurate, but it will cause great harm to the human body. This method will only be considered when the crowd is undergoing surgery. [0004] Non-invasi...
