Claim 0:
1. A method for characterizing atrial fibrillation comprising:
determining, by a processor of a computing device and based on heart data, an earliest activation time of a heart being monitored;
determining, by the processor and based on the heart data, a latest activation time of the heart;
modeling, by the processor, the earliest activation time and the latest activation time within one or more activation time maps;
identifying, by the processor, one or more rotational activity trajectories based on the one or more activation time maps;
identifying a plurality of propagation line patterns based on the one or more rotational activity trajectories;
forming a polygon from the plurality of propagation line patterns; and
identifying, by the processor, an atrial fibrillation driver based at least in part on the polygon.
