Embodiment Construction
[0053] like figure 1 Described flow chart, a kind of electrocardiographic signal real-time QRS wave detection method provided by the present invention, comprises the following steps:
[0054] Step 1, the electrocardiographic signal is preprocessed to obtain the data of the denoised electrocardiographic signal, and the data includes a plurality of cycles;
[0055] Step 2, R wave detection, using the slope method to detect the R wave on the denoised ECG signal, and using the average RR interval to correct the detection result to obtain the position and amplitude of the R wave;
[0056] Step 3, Q wave detection, adopting the differential method to detect the position and amplitude of the Q wave according to the position of the R wave;
[0057] Step 4, S-wave detection, using the minimum value method to detect the position and amplitude of the S-wave according to the position of the R-wave.
[0058] The data used in this example is collected through a single-lead wearable sports...
