Characterization of Electrograms from Multipolar Diagnostic Catheters during Atrial Fibrillation

Figure 3

Simulation results: (a) L4 is the location of the known RotA source. The circles show the MPDC at the start point (L1) of each of Paths A to E; in every step of each path, the MPDC moves forward towards the RotA source; (b) the electrograms show the conduction pattern of path A from L1 to L4. The TCD increases from 106 ms to 228 ms, as reported on the top of each MPDC electrogram. The numbers at the left corner indicate the lead number of the corresponding bipole electrode of the MPDC.
