1. One or more computing systems for displaying indications of a possible source location of an arrhythmia within a heart of a patient, the one or more computing systems comprising:
one or more processors; and
one or more memories storing instructions, which when executed by the one or more processors, cause operations comprising:
accessing a patient cardiogram of the patient;
identifying patient cycles of the patient cardiogram that represent an arrhythmia;
for each of a plurality of the patient cycles, identifying a source location of the arrhythmia for that patient cycle;
for each of a plurality of areas within the heart, calculating a percent of patient cycles with identified source locations that are within that area; and
displaying a graphic with, for one or more of the areas, a coding that is based on the percent of patient cycles with identified source locations that are within that area.
