Method for analyzing an electrogram

Abstract

A method for analyzing an electrogram (1), via a control system, that has been recorded via a catheter inserted into a human body, which includes multiple electrodes. At least one channel (K) of the electrogram has been recorded by, preferably between, the electrodes. The control system detects activation candidates (3) in a first channel (K_a). Multiple different potential sequences (4) of activation candidates are defined along the time dimension (5) of the first channel. The control system assigns costs including one or more independent cost components to the potential sequences, selects a sequence of dominant activations from the potential sequences of the first channel, selects the sequence of dominant activations that fulfills an optimization criterion based on the costs of the potential sequences, and assigns cost components to activation candidates. The costs of the potential sequences include the cost components of the activation candidates defining the respective potential sequence.
