Annotation: The surgical complex is developed to search arrhythmogenic sources by multichannel epicardial mapping. We describe the algorithm and the method of finding of a multiple arrhythmogenic source in the treatment of atrial fibrillation based on the interpolation results of multi-port measurements and visualization of these data on a heart model in the process of multi-channel recording in the time domain, the spatial distribution of the frequency atrial activity, the spatial distribution of the maximum amplitudes of potentials.
