Figure 1 Posterior view of the right atrium. On left panel, blue dots represent areas of phrenic capture as well as eventual cryoablation lesions. The catheter tip shown is the cryocatheter. Pink and red lesions represent initial failed radiofrequency ablations, which were slightly adjacent to the area of early activation and phrenic capture. Right panel demonstrates activation point of the earliest atrial premature contraction with pre-P wave on ablation distal (MAP1, 2) with QS on unipolar (MAP1).
