A flow chart describing the basic AF driver location algorithm. When starting the algorithm, the simplified CMP model is run with one or two drivers placed at random locations—the algorithm could easily be extended to more drivers if desired as outlined in figure 7. A random position is chosen to record the first set of electrograms. Search regions are constrained as described in appendix D. Predictions from the X and Y regressors are forced to lie within search constraints. ‘Prediction error’ initiates if the constraint region becomes too small or predictions loop between repeated coordinates.
