Pace-making electrocardio-signal non-equilibrium deep compression method

Abstract

The invention relates to a pace-making electrocardio-signal non-equilibrium deep compression method which comprises the steps of conducting rapid content sensing of pace-making electrocardio signals, and conducting non-equilibrium synergy data compression and reconstitution on representation waveforms and non-representation waveforms. According to the pace-making electrocardio-signal non-equilibrium deep compression method, in order to solve the problems that pace-making pulses and other electrocardio waveform frequencies are large in distributional difference and the weight difference exists in the representation waveforms and the non-representation waveforms in clinical diagnosis, different compression and reconstitution strategies can be used for the representation waveforms and the non-representation waveforms in a targeted mode on the premise that requirements of the Nyquist sampling theory are not met. According to the pace-making electrocardio-signal non-equilibrium deep compression method, 1 / 2 of the inherent frequency of pace-making pulse signals is used for sampling, compressed sensing and Huffman encoding processing are carried out on the representation waveforms in the same time window, and non-distortion sampling and Huffman encoding are carried out on the non-representation waveforms in the same time window. On the premise that non-distortion of the clinical diagnosis message is guaranteed, the compression ratio and the reconstitution accuracy of data are improved, and the reliable operation of a wireless monitoring terminal of a pacemaker is guaranteed.
