Figure 4 The Successful Ablation Site in the LCC (Case 8)
The local ventricular activation preceded the onset of the QRS by 24 ms, and the unipolar electrogram showed a QS pattern at the successful ablation site. The pink line indicates the coronary angiographic catheter deployed in the left coronary artery (LCA). ABL = the ablation catheter in the left coronary sinus cusp; LAO = left anterior oblique; RAO = right anterior oblique; RVA = right ventricular apex; RVOTd/p = the distal/proximal electrode pairs of the right ventricular outflow tract catheter; other abbreviations as in Figures 1 and 2.
