Figure 1:

Study Flow. a. Left and Right Atria in the Heart and Torso. b. Basket Catheters used to record signals globally within both atria in a 67-year-old woman with persistent AF, showing atrial shell and therapy (ablation) site. c. AF termination on 64 electrodes inside the heart by treating site in b., terminating to normal (sinus) rhythm. d. Spatial maps of activation phase in AF in the entire left atrium, shown as 8×8 grids (interpolated for clarity) colorized from 0 to 2π. Sampled 4×4 tiles may show e. presence of rotational features, such as where therapy terminated AF, or their absence. f. Spatial maps of phase every 5 ms for 1000 ms (200 total per patient).
