1. A computer-implemented method for identifying a cause of a heart rhythm disorder, the method comprising:
- computing diagnostic values from data received from a plurality of sensor locations corresponding to a plurality of points within a cardiac anatomy;
comparing the diagnostic values for each of the plurality of points within the cardiac anatomy to a reference comprising previously-stored diagnostic values to assign probability values indicating a likelihood that the cause of the cardiac rhythm disorder is associated with the points, the likelihood being associated with a rate of activation at each point;
generating a probability map based on the probability values in relation to the plurality of points within the cardiac anatomy; and
generating a clinical representation based on the probability map indicating the likelihood that one or more points within the cardiac anatomy corresponds to the cause of the heart rhythm disorder.

Abstract
A method of analyzing a complex rhythm disorder in a human heart includes accessing signals from a plurality of sensors disposed spatially in relation to the heart, where the signals are associated with activations of the heart, and identifying a region of the heart having an activation trail that is rotational or radially emanating, where the activation trail is indicative of the complex rhythm disorder and is based on activation times associated with the activations of the heart.
