Abstract:
1. A method for dividing a substantial cyclic cardiovascular signal into segments by determining the characteristic of said cyclic signal, wherein each cycle in said signal comprises at least two characteristic segments and wherein the method comprises the steps of: providing a substantially cyclic cardiovascular signal obtained from a patient; identifying at least two characteristic segments in a cycle of said cardiovascular signal based on prior knowledge of said segments' characteristics; verifying said identified segments based on a number of statistical parameters obtained from prior knowledge relating to said cyclic signal, said verifying including the step of calculating a probability that said identified segments are at least one predetermined type defined from prior knowledge of said segments using said statistical parameters; said step of calculating the probability that said identified segments are at least one predetermined type defined from prior knowledge is based on Bayesian statistics; and using information relating to the verified segments to directly or indirectly diagnose the patient.
