Searching for order in atrial fibrillation using electrogram morphology recurrence plots
Recurrence plots show patterns within atrial fibrillation electrograms. Recurrence plot diagonal and vertical lines indicate determinism and stationarity. Wide range of morphology recurrence rates seen in canine atrial fibrillation model. Shuffling electrogram order simulates random timing of electrogram recurrence.
