METHOD AND DEVICE FOR PROCESSING ELECTROCARDIO SIGNALS

Document Type and Number:

WIPO Patent Application WO/2017/096597

Kind Code:

A1

Abstract:

A method and device for processing electrocardio signals. The method comprises the following steps: obtaining a sample sequence which represents electrocardio signals (S100); denoising the sample sequence (S200); geometrically compressing the denoised sample sequence, and discarding a sample which does not have geometrical characteristics (S300), wherein the sample which does not have geometrical characteristics refers to the sample which is not an extreme value as compared with the currently adjacent samples at left and right and deviates, within a predetermined range, from a straight line determined with respect to the left and right samples. The device comprises a sample sequence obtaining module (610), a denoising module (620), and a geometrical compressing module (630). By means of the method, a denoised sample sequence is compressed by means of geometrical compression, such that the calculation is simple, the processing is efficient, and the number of samples is greatly reduced while the geometrical characteristics of signals are maintained.
