Claim 10:
11. A system to characterize atrial fibrillation, the system comprising:
a memory configured to store heart data;
a processor operatively coupled to the memory and configured to:
determine, based on heart data, an earliest activation time of a heart associated with the heart data;
determine, based on the heart data, a latest activation time of the heart;
model the earliest activation time and the latest activation time within one or more activation time maps; and
identify one or more rotational activity trajectories based on the one or more activation time maps;
identify a plurality of propagation line patterns based on the one or more rotational activity trajectories;
form a polygon from the plurality of propagation line patterns; and
identify an atrial fibrillation driver based at least in part on the polygon.
