FIGURE 1. Display of 3-dimensional unipolar voltage maps in shallow left anterior oblique projection acquired using NOGA catheter mapping system. (A) Map was done at baseline before laser therapy and shows normal unipolar voltage. (B) Map was done during laser therapy. White points on left ventricular map represent mapping points, and orange dots represent sites of laser administration to endocardial surface of anteroapical wall. Color bars represent 5 (orange) to 15 (blue/purple) mV. White disk represents animal’s head and is placed for orientation.
