Abstract:
1. A system to reconstruct cardiac information 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 a plurality of sensors spatially related with 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, the confidence threshold associated with a predetermined percentage of beats having discernible activation onsets out of total beats associated with each of the high and low confidence signals; determine an activation onset associated with at least one low confidence signal within an acceptance time window, the acceptance time window associated with the low confidence signal indicating an earliest activation and a latest termination for a beat in the low confidence signal; order the activation onsets associated with the high and low confidence signals to indicate the source of the complex rhythm disorder; and treatment means for modifying the indicated source.
