Abstract

The application discloses a method and device for identifying characteristic points of radial artery pressure waveform dicrotic waves. The method comprises the steps of performing wave filtering treatment on radial artery pulse waveforms; generating radial artery pulse waveform differential signals, and determining the maximum value of the differential signals; based on the maximum value of the differential signals, determining the starting point of the radial artery pulse waveform; based on the starting point, determining the cycle of the radial artery pulse waveform; based on the starting point, performing baseline drift removal treatment on the radial artery pulse waveform, and demarcating the waveform; and identifying the demarcated waveform dicrotic wave characteristic points. According to the method, the treatment process for the pulse waveform data is reduced to a certain extent, the computational resource consumption is reduced, and the waveform characteristic points are easy to extract, so that the subsequent analysis treatment process using the pulse waveform is more convenient.

Description

technical field [0001] The present application relates to the field of waveform detection, in particular to a method and device for identifying dicrotic wave characteristic points of radial artery pressure waveform. Background technique [0002] Nowadays, with the continuous development of the economic level, people's living standards continue to improve, and their sense of happiness continues to increase. But behind these, due to the fast-paced modern life, unreasonable dietary nutrition structure, and the increasingly common phenomenon of population aging, the incidence and mortality of cardiovascular diseases are increasing day by day. According to the American Heart Association (AHA), cardiovascular disease (CVD) caused 830,000 (836,546) American deaths in 2017, and 1 out of every 3 deaths was due to CVD. 2,300 people die from CVD every day, an average of one death every 38 seconds. Cardiovascular disease kills more people each year than all cancers and chronic lower r...
