Problems solved by technology

[0002] When measuring ECG in the field of ECG detection, the quality of ECG signal is the prerequisite for effective analysis of ECG. ECG signal with poor signal quality will mislead ECG analysis, especially in single-lead portable ECG acquisition. Prominent, because the single-lead portable ECG acquisition has sudden waveform jitter, motion artifacts, and easy introduction of noise such as large power frequency interference
[0003] In order to realize the correct analysis and diagnosis of ECG, the quality of ECG waveform must be good. Excessive noise and large jitter will lead to the deterioration of the accuracy of ECG automatic analysis and judgment, and the occurrence of false detection and missed detection.

Embodiment

[0157] Such as Figure 14 Shown, a kind of analysis method based on the detection method of ECG QRS complex width of the present invention comprises the steps:

[0158] S1. Obtain 10 seconds of ECG waveform to be analyzed;

[0159] S2. According to the ECG signal quality identification method, the quality of the ECG waveform to be analyzed is evaluated, and the ECG waveform quality level for 10 seconds is obtained. The ECG waveform quality evaluation takes 1s as a unit, and a total of 10 data are obtained representing the first second. Quality rating factor up to 10th second;

[0160] Such as Figure 12 As shown, the ECG signal quality identification method includes the following steps:

[0161] S201. Obtain the original ECG waveform amplitude data with a sampling rate of fs, and divide the ECG waveform amplitude data into processing segments X with 10 seconds as the time unit;

[0162] S202. In the processing section X, segment the ECG signal into segments in units of 1 s...

Abstract

The invention discloses a method for detecting an electrocardiogram QRS wave group width. The method comprises the steps of searching for peaks and troughs in a QRS wave by using an extremum method, and according to an extremum point found, the combined gradient, a triangle method, an equipotential section potential value and amplitude information, determining the start and end points of the QRS wave group, wherein the start and end points of the QRS wave group are the width of the QRS wave group. Accurate detection of the width of the electrocardiogram QRS wave group has significant effect oncardiac function tests and diagnosis and prevention of cardiovascular diseases.

Description

technical field [0001] The invention relates to the identification of QRS wave groups in electrocardiographic signals, in particular to a method for detecting the width of electrocardiographic QRS wave groups and an electrocardiographic analysis method thereof. Background technique [0002] When measuring ECG in the field of ECG detection, the quality of the ECG signal is the premise of effective ECG analysis. The ECG signal with poor signal quality will mislead the ECG analysis, especially in single-lead portable ECG acquisition. Prominent, because single-lead portable ECG acquisition has sudden waveform jitter, motion artifacts, and noise such as large power frequency interference. [0003] In order to realize the correct analysis and diagnosis of ECG, the quality of ECG waveform must be good. Excessive noise and large jitter will lead to poor accuracy of ECG automatic analysis and judgment, and false detection and missed detection will occur. In order to take into accoun...
