An example of the respective maps in the same patient
(A)The CARTOFINDER map . The green area represents focal activation color-coded based on number of repetitions of the focal activations. White rings represent the center of the PentaRay catheter positioned at the time of the recording. (B) The DCL map . The DCL map was created using LAT map algorithm, converting the DCL into LAT at each recording site which was identical to the white ring site. The color-coded DCL map shows the spatial distribution of DCL during AF. The shortest DCL is indicated in red and the longest DCL is indicated in purple. (C) Combination map of the focal activation and DCL maps . Green squares indicated by arrows represent points with focal activations. The red-colored area represents the lower half of the DCL range, whereas the purple-colored area shows the higher half of the DCL range. The DFAs are defined as focal activations located in the red-colored area. In this case, focal activations were recorded in the PV antrum, anterior, inferior, and left atrial appendage ostium, and DFAs were found only in the PV antrum. In this case, AF was terminated to sinus rhythm during pulmonary vein isolation.
DCL, dominant cycle length; LAT, local activation time; DFAs, dominant focal activations
