1. A method for identifying a disease of a patient, the method comprising: collecting data of at least one cardio-respiratory function of the patient over time; eliminating artifacts from the collected data to create a new data record; constructing a phase-space from the new data record; constructing a hypercube covering the phase-space; calculating threshold criteria for quantifying dispersion characteristics of an attractor of the phase-space; and determining the patient's tendency towards the disease based on the threshold criteria.
