[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

Embodiment

[0157] Such as Figure 15 Shown, a kind of ECG analysis method based on the detection method of ECG QRS complex 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 13 As shown, its central electrical 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...

Abstract

The invention discloses a method for detecting an electrocardiogram QRS wave group. The method comprises the steps of using an extremum method to find peaks and troughs in a QRS wave, according to anextremum point found, and combining an equipotential step potential value and amplitude information to detect each sub-waveform in the QRS wave group so as to determine the time position of the QRS wave group so that QRS wave group forms can be clearly displayed and the heart rate can be calculated; the accurate detection of the QRS wave group is the basis for the automatic diagnosis of an electrocardiogram. After the detection of the QRS wave group is determined, it is possible to calculate the heart rate, that is, the number of heart beats per minute, heart rate variability and other electrocardiogram time interval measurement and amplitude measurement.

Description

technical field [0001] The invention relates to the identification of QRS wave groups in electrocardiographic signals, in particular to a detection method 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 account the advantag...
