Abstract :
An artificial neural network was trained to detect local activations during the first 2 sec of an induced ventricular fibrillation performed on five pigs. A rule based method (RBM) and methodology based on the transmembrane current (TCM) were used to validate the data for training/testing the network. With appropriate pre- and post-processing, the neural network yielded encouraging results when trained and tested on a portion of the data. A stop training technique was implemented to avoid over-training the network
