Analysis of unipolar electrograms and DCL on the CARTOFINDER system
(A) Annotation Algorithm Shaded regions represent the WOI defined
by the total activation phase of the bipolar electrogram. The yellow
dots represent each annotation point on the unipolar electrogram. White
double-headed arrows represent the CL. (B) Schema of DCL. The
white bars represent the annotations of each channel. (C) Screen
of the unipolar recording. In this example, the unipolar channel Pen 7
shows frequent repetitive focal activation. White arrows represent
consecutive QS patterns that occur earlier than their neighboring
electrodes. WOI, window of interest; DCL, dominant cycle length; CL,
cycle length
