Characterization of Electrograms from Multipolar Diagnostic Catheters during Atrial Fibrillation

Figure 1

Computer simulation study: (a) RotA wave with the MPDC at location L1 which has the first activated bipole at bipole 6 indicated with the arrow pointing towards it. (b) The electrograms at location L1. The numbers at the left corner indicate the lead number of the corresponding bipole electrode and the asterisk denotes the first activated bipole (FAB). The conduction delay between bipole 5 and the FAB and the cycle length are indicated.
