1. the electrocardiosignal QRS complex detection method based on wavelet transformation comprisesStep S1 carries out pretreatment to electrocardiosignal, the sample rate of electrocardiosignal is changed into the sample rate of preset range;

  • Step S2 carries out wavelet transformation to pretreated electrocardiosignal, obtains the characteristic frequency spectrum radio-frequency component;

    It is characterized in that, also comprise;

    Step S3 is to the differentiate of characteristic frequency spectrum radio-frequency component and take absolute value;

    Step S4, interference is rejected to small-signal, keeps the maximum point of differentiate absolute value;

    Step S5 according to the variation of maximum point amplitude, obtains signature waveform in conjunction with the maximum cycle of QRS complex wave.
