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
