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...
