Abstract
There is provided a method to estimate a period characteristic, such as period length or a period location, of a physiological rhythm, such as a cardiac rhythm or a spontaneous breathing rhythm. The method comprises receiving the signal representing the physiological rhythm, estimating a first group of period characteristic estimations based on the signal, generating a prior probability for the period characteristic based on at least a subset of the first group of period characteristic estimations, and estimating a second group of period characteristic estimations based on the first group and the prior probability. By using this method, the accuracy of the signal is improved, especially when the signal is obtained from an accelerometer arranged on the chest of the subject.
