Claim:
A rapid method for analyzing a bio-signal instantaneously by phase space difference, comprising the following steps: (A) selecting a suitable parameter configuration; (B) establishing a one phase space matrix for reference and another phase space matrix for analyzing the bio-signal, wherein establishing the one phase space matrix for reference and analyzing phase space matrices includes: (a) eliminating a noise interference in the bio-signal, (b) employing a parameter of a size of the phase space matrix as a basis of a normalization factor, (c) conducting a normalization process on an amplitude of the bio-signal, (d) employing the normalization factor to configure the size of the phase space matrix, and initializing the contents in the phase space matrix as zero, (e) configuring a plurality of origin coordinates as coordinates of a datum point, (f) employing the parameter of a time interval and the datum point to configure the coordinates of a reference point, (g) employing a strength of the bio-signal at the datum point and the reference point to label the two coordinates of the phase space matrix, and adding the values in a location of the coordinates, and (h) sequentially adding the datum point and the reference point to establish the phase space matrix; (C) calculating a variance condition for the label points between the two space matrices to obtain a variance of a chaotic phase space difference; and (D) evaluating whether the chaotic phase space difference exceeds a threshold range, wherein when a complexity difference of the chaotic phase space difference exceeds the threshold range, the bio-signal is considered to be abnormal, and when the complexity difference of the chaotic phase space difference does not exceed the threshold range, the bio-signal is considered to be normal.
