Abstract

The invention relates to an electrocardiosignal processing method based on signal segmentation smoothing. The method comprises the following steps of S1, original signal acquiring: collecting and acquiring original data of an electrocardiosignal, and marking the original data as ECG<raw>; S2, electrocardiosignal preprocessing: performing preprocessing operation on the ECG<raw> to obtain an outputsignal, and marking the output signal as ECG<filtered>; S3, QRS feature recognition: performing QRS wave group feature point recognition operation on the ECG<filtered>; S4, segmentation linear smoothing: performing segmentation linear smoothing filtering operation on the ECG<filtered> to obtain an output signal, and marking the output signal as ECG<smooth>; S5, global second-order smoothing: performing global second-order smoothing filtering operation on the ECG<smooth>, and acquiring and outputting the electrocardiosignal. The electrocardiosignal processing method has the advantages that therequirements of removing high-frequency noise, removing movement interference and realizing signal waveform smoothing are met at the same time; the electrocardiosignal processing method is applicableto occasions with high electrocardiosignal quality requirement; the quality of the processed electrocardiosignal is high.

Description

technical field [0001] The invention relates to the field of digital signal processing of bioelectrical signals, in particular to a method for processing electrocardiographic signals based on signal segment smoothing. Background technique [0002] The ECG signal is an important vital sign signal of the human body. The signal is obtained by measuring the potential difference on the surface of the human body through a bioelectrode. It can be used to reflect the working state of the heart and internal characteristic information, so as to make a rapid diagnosis of cardiovascular related diseases. [0003] The ECG signal is a very weak electrical signal. The original ECG signal is easily submerged in all kinds of noise generated during the acquisition process. Therefore, it is necessary to perform signal processing operations on the ECG signal to achieve the accuracy for disease analysis and diagnosis. need. Digital signal processing technologies commonly used in the field of EC...
