Figure 2

A: Fibrillar atrial myocardium potentials (heterogeneous and coarse segmented spectrum) (arrow) on intracardiac electrograms. B: Compact atrial myocardium potentials (homogeneous spectrum) on intracardiac electrograms. Bipolar endocardial electrograms are displayed at filter settings of 300–500 Hz at a sweep speed of 400 mm/s. ABLd = distal electrode of ablation catheter ; ABLp = proximal electrode of ablation catheter; CSd = distal electrode of coronary sinus catheter; CSp = proximal electrode of coronary sinus catheter.
