Systems are provided for generating data representing the electromagnetic state of the heart for medical, scientific, research, and / or engineering purposes. The system generates data based on the dimensions of the heart and the source configuration, such as the location of scar or fibrosis or arrhythmic substrates within the heart, and a computational model of the electromagnetic output of the heart. The system can dynamically generate source configurations to provide representative source configurations that can be found in the population. For each source configuration of the electromagnetic source, the system performs a simulation of the movement of the heart to model the source configuration electromagnetic output (eg, the electromagnetic mesh of each simulation step, with an electric potential at each point of the electromagnetic mesh. Have) to generate. For each source configuration, the system can be used to generate a heart rate curve from the modeled electromagnetic output of that source configuration and to predict the location of the source of the arrhythmia.
