Claim:
1. A system for analyzing a cardiac electrogram of an atrial fibrillation comprising: an electrogram device for taking, delivering, or storing a cardiac electrogram of an atrial fibrillation; a processor in electronic communication with the electrogram device; a memory in electronic communication with the processor, wherein the memory comprises programming code for execution by the processor, and the programming code is configured to: iteratively determine cycle lengths between activation peaks of the cardiac electrogram of the atrial fibrillation, applying iteratively adjusted detection threshold levels, until a mean of the determined cycle lengths meets at least one criteria; and determine an atrial fibrillation cycle length of the atrial fibrillation when the mean of the determined cycle lengths meets the at least one criteria; and a device for treating a site of atrial fibrillation sources based on the determined atrial fibrillation cycle length.
