Figure S1. Example of three successful ablations of premature ventricular contractions originating from the distal GCV, LCC, and subvalvular LVOT, respectively. A: Activation time (30 ms before QRS onset) at the GCV of case 1 with VAs originated from the distal GCV. B: Activation time (24 ms before QRS onset) at the LCC of case 2 with VAs originated from LCC. C: Activation time (28 ms before QRS onset) beneath LCC of case 3 with VAs originated from the distal GCV. B: Activation time (24 ms before QRS onset) at the LCC of case 2 with VAs originated from subvalvular LVOT. ABL d (p), the distal and proximal electrode pairs of the ablation catheter; GCV, great cardiac vein; LCC, left coronary cusp; LVOT, left ventricular outflow tract. (JPG 162 kb)
