Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0030] Example.
[0031] A method for recognizing ventricular fibrillation based on machine learning technology, comprising the following steps:
[0032] (1) Preprocess the ECG signal to filter out noise such as baseline drift and power frequency interference, and resample the denoised ECG signal to a fixed sampling rate;
[0033] (2) Carry out band-pass filter analysis on the ECG signal after denoising and resampling, and calculate feature 1. The center frequency of the band-pass filter is 14.6 Hz, which is realized by using an integer coefficient digital filter; the specific method is as follows: assume a band-pass filter The output of FS is FS, and for each secon...
