Embodiment Construction

[0034] The present invention will be further described below according to accompanying drawing.

[0035] Such as figure 1 — image 3 Shown is a flow chart of the method for processing ECG signals in the present invention.

[0036] Step S1: Read a complete cycle of paper-based ECG waveforms, digitize the data and extract the ECG waveform data, which is defined as MN segment, M point is the starting point of the waveform, and N point is the ending point of the waveform ;

[0037] The paper ECG waveform in this step comes from the authoritative ECG library or ECG spectrum books, select a typical ECG waveform of a cycle, use the Engauge Digitizer software to manually trace the paper ECG, and extract the ECG waveform on the ECG drawing Data, using the typical ECG waveform data as the ECG template data, the typical ECG waveform can be the ECG waveform of a normal person, or it can be the typical ECG waveform of a common disease (myocardial ischemia).

[0038] Step S2: Process th...

Abstract

A method for processing ECG signals that can be edited, comprising: step S1: read a cycle of paper / electronic ECG waveforms, and extract the ECG waveform data; step S2: use low-pass filtering to process the ECG Electrical waveform data; step S3: use the maximum value of the slope change rate and the maximum value of the voltage to determine the position of the R point of the R wave; step S4: determine the position of the Q point of the Q wave and the position of the S point of the S wave; step S5: use the slope activity threshold method Extract the control points of the MQ segment and the SN segment respectively, and the number of control points ranges from 3 to 6; step S6: use linear interpolation method and quadratic B-spline method to fit and reconstruct the ECG waveform; use a small number of control points to fit The ECG waveform can be locally adjusted. The segmental interpolation method combining linear interpolation and quadratic B-spline can realize the fitting of sharper R wave; and by adding the mouse to the control point, press and drag Event, the user can perform arbitrary operations on the control point.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method for processing electrocardiographic signals which can be edited. Background technique [0002] The ECG signal is one of the important bioelectrical signals of the human body. It reflects the working state of the heart and reliable internal characteristic information from different levels. Through the classification and recognition of the ECG signal, it is convenient to quickly diagnose heart diseases. [0003] There are two main application directions of existing ECG waveform fitting methods: for ECG signal feature extraction, classification analysis and ECG waveform simulation; at present, the fitting and reconstruction of ECG waveforms include linear approximation and curve fitting. The waveform reconstructed by the linear approximation method is not smooth. If the approximation degree is increased, a large number of data points is required, and the...
