1. A system to reconstruct cardiac information representing a complex rhythm disorder associated with a patient'"'"'s heart to indicate a source of the complex rhythm disorder, the system comprising:
- at least one computing device configured to;
receive cardiac information signals from the patient'"'"'s heart during the complex rhythm disorder,classify the cardiac information signals into high and low confidence signals, wherein the high and low confidence signals are separated by a confidence threshold,determine activation onsets associated with the low confidence signals within an acceptance window;
order the activation onsets associated with the low confidence signals and activation onsets associated with the high confidence signals; and
output the activation onsets associated with the high and low confidence signals to indicate a source of the complex cardiac rhythm disorder.
