System for characterizing a heart rhythm and associated method

A method for characterizing a heart rhythm comprising:

• when a selection among indicators of probability of presence of sets of indicators of probability of presence consists of the indicators of the sets of indicators of probability of presence, generating, for each arrhythmia of the plurality of arrhythmias, using a set of elementary classifiers, a set of indicators of probabilities of presence of the arrhythmia over a time window using descriptors of a set of at least one lead of an electrocardiogram of a patient acquired over the time window, so as to generate the indicators of the sets of indicators of probability of presence,
• when the selection comprises an incomplete part of the indicators of probability of presence of the indicators of probability of presence of the sets of indicators and is not empty, generating each indicator of the selection using at least one of the elementary classifiers using at least one descriptor of at least one lead of the set of at least one lead,
• generating an input vector, the components of the input vector comprising, among the indicators of the sets of indicators of probability of presence only each indicator of probability of presence of the selection,
• generating, using a global classifier, global indicators of probability of presence of arrhythmias in the time window from the input vector,
• generating, using a global classifier, global indicators of probability of presence of arrhythmias in the time window from the input vector,
• selecting or deselecting at least one of the indicators of probability of presence so that the selection is composed of each selected indicator of probability of presence.
