Confirmed Driver With Rotational Activity

(A to D) Still CARTOFINDER maps demonstrating an AF driver with rotational activity along the anterior wall and the corresponding unipolar electrograms obtained from the basket catheter. This is a good example of real-world unipolar electrograms acquired during AF being annotated by the CARTOFINDER system. It could be debated whether certain deflections should be annotated or not, but with 64 poles this makes up a small proportion of complexes and did not impede generation of maps overall. MVA = mitral valve annulus; other abbreviations as in Figures 1 and 2.
