Fig. 1
Novel omnipolar activation map (A) and voltage map (B) during tachycardia. Note that slow continuous activation at the bottom of the inferior LIPV was clearly displayed in the low voltage area (red arrow). Magnification of the area of interest (white dotted square) and automatically acquired electrograms in this region (C) demonstrated that continuous activation was displayed in a sequence of (i)→(ii)→(iii), suggesting reentrant activity.
Fig. 2
Fig. 2
Conventional bipolar activation map (A) and voltage map (B) during tachycardia. Note that slow continuous activation at the bottom of the inferior LIPV was not observed, and instead, centrifugal activation from the lateral LA (yellow star) was observed. Magnification of the area of interest (white dotted square) and automatically acquired electrograms in this region (C) demonstrated that discrete activation was displayed in a sequence of (iii)→(ii)→→→(i). Suggesting focal activity.
