Characterization of Electrograms from Multipolar Diagnostic Catheters during Atrial Fibrillation

Figure 4

Variation of total conduction delay. Variation in TCD with respect to the MPDC location: (a) In simulation study, the TCD shows an increasing gradient as the MPDC moves from L1 towards the RotA at L4, in all the paths. (b) The plot demonstrates the increasing gradient of TCD in the clinical study, in both Path A and Path B when the MPDC moves from L1 to LRotA, with the location of every successive step directed towards the first activated bipole of the current location.
