Patent ID: 7120485

Claim:
A method for detecting cardiac arrhythmia comprising: detecting RR intervals of a patient, wherein each RR interval is an interval between two heart beats; constructing standard histograms of ΔRRs collected during cardiac arrhythmia of a plurality of subjects, wherein each ΔRR is a difference between two successive RR intervals; constructing test histograms of ΔRRs of the patient from the detected RR intervals of said patient, wherein the standard and test histograms are probability density histograms; calculating a mean value of a given number of successive RR intervals of the patient; choosing one of the standard probability density histograms in relation to said mean value, wherein choosing one of the standard probability density histograms comprises selecting the standard histogram corresponding to the range of RR intervals in which said mean value is located; and comparing said standard and test histograms to detect whether said patient suffers from cardiac arrhthymia.
