Claim:
1. An arrhythmia detecting method adopted in an arrhythmia detection apparatus, comprising: a) obtaining a pulse period sequence and a pulse amplitude sequence through a cuff of the arrhythmia detection apparatus, and in which to obtain a plurality of pulse periods and a plurality of pulse amplitudes through a pulse period and a pulse amplitude measurement module of the arrhythmia detection apparatus; b) comparing similarities of any two of the pulse periods and any two of the pulse amplitudes for respectively generating similarity statistical comparison values through a comparison generating module of the arrhythmia detection apparatus, wherein each of the generated similarity statistical comparison values is 1 if the two compared pulse periods or the two compared pulse amplitudes are similar, and is 0 if the two compared pulse periods or the two compared pulse amplitudes are dissimilar; c) calculating a statistic value comprising a set of the similarity statistical comparison values corresponding to the similarities of the pulse periods and another statistic value comprising a set of the similarity statistical comparison values corresponding to the similarities of the pulse amplitudes through a judgment generating module of the arrhythmia detection apparatus; d) establishing an arrhythmia analysis matrix according to the statistic values, the pulse period sequence and the pulse amplitude sequence through the judgment generating module, wherein the arrhythmia analysis matrix(AAM) is  where Z e) determining an atrial fibrillation, through a type determination module of the arrhythmia detection apparatus, when a coefficient of variation Var(Z f) determining, through the type determination module, if the coefficient of variation Var(Z g) determining, through the type determination module, a premature contraction when multitude continuous dissimilar pulse periods or pulse amplitudes are detected if the coefficient of variation Var(Z h) determining, through the type determination module, a tachycardia if the pulse period average Mean (PP i) determining, through the type determination module, a bradycardia if the pulse period average Mean (PP j) determining, through the type determination module, and classifying a non-specified arrhythmia if the arrhythmia cannot be determined in the step e, the step g, the step h, and the step i.
