Abstract
The invention relates to a method and a device for the automated detection and differentiation of cardiac rhythm disturbances. According to said method, measured values for a coherent series of a cardiac frequency signal, preferably the times of the peaks of the R waves are correlated together using a Poincar model and the correlated data transformed into a multi-dimensional phase space and represented as a Lorenz curve. The data transformed into the phase space is morphologically characterised and assigned to particular pre-determined patterns by means of case-based reasoning. Particular clinically-relevant rhythmic or arrhythmic forms can be determined from the assigned patterns by means of empirically-determined relationships.
