First Claim
1. A method performed by a computing system for generating a representation of an electromagnetic source, the method comprising:
- identifying modeled derived electromagnetic data that matches patient derived electromagnetic data of a patient, the modeled derived electromagnetic data derived from modeled electromagnetic output of the electromagnetic source generated using a computational model of the electromagnetic source, the modeled electromagnetic output having, for each of a plurality of time intervals, an electromagnetic value for locations of the electromagnetic source;
identifying a cycle within the modeled electromagnetic output from which the matching modeled derived electromagnetic data was derived;
for each of a plurality of display locations of the electromagnetic source, generating a display electromagnetic value for that display location based on the electromagnetic values of the modeled electromagnetic output of the identified cycle; and

Abstract
Systems are provided for generating data representing electromagnetic states of a heart for medical, scientific, research, and/or engineering purposes. The systems generate the data based on source configurations such as dimensions of, and scar or fibrosis or pro-arrhythmic substrate location within, a heart and a computational model of the electromagnetic output of the heart. The systems may dynamically generate the source configurations to provide representative source configurations that may be found in a population. For each source configuration of the electromagnetic source, the systems run a simulation of the functioning of the heart to generate modeled electromagnetic output (e.g., an electromagnetic mesh for each simulation step with a voltage at each point of the electromagnetic mesh) for that source configuration. The systems may generate a cardiogram for each source configuration from the modeled electromagnetic output of that source configuration for use in predicting the source location of an arrhythmia.
