Abstract:
1. A system for determining a direction of conduction of an arrhythmia episode between a first cardiac region and a second cardiac region, the system comprising: a first electrode to sense a first signal indicative of first contractions in the first cardiac region; a second electrode to sense a second signal indicative of second contractions in the second cardiac region; a first contraction detector circuit, coupled to the first electrode, to detect the first contractions; a second contraction detector circuit, coupled to the second electrode, to detect the second contractions; a cardiac data analyzing circuit coupled to the first contraction detector circuit and the second contraction detector circuit, the cardiac data analyzing circuit adapted to: a cycle length pairing circuit coupled to the cardiac data analyzing circuit, the cycle length pairing circuit adapted to pair the first cycle lengths with the second cycle lengths in first and second directions during the arrhythmia episode having the one-to-one association of the first contractions to the second contractions, the first direction corresponding to a direction of conduction of the arrhythmia episode from the first cardiac region to the second cardiac region, the second direction corresponding to a direction of conduction of the arrhythmia episode from the second cardiac region to the first cardiac region; and a processor coupled to the cycle length pairing circuit, the processor adapted to:
