From: Trans-subclavian approach for radiofrequency ablation of premature ventricular contractions originating from subtricuspid annulus: a case report

Figure 2

Surface and intracardiac electrograms recordings, and fluoroscopic images obtained at the lateral subtricuspid annulus via the right femoral vein. (A) The local ventricular activation time preceded the onset of the QRS complex was 24 ms. (B) Pace mapping at the same site. (C) Fluoroscopic images obtained in the left anterior oblique and right anterior oblique projection. ABL d (p) = the distal (proximal) electrode pair of ablation catheter; CS = coronary sinus; RVA = right ventricular apex.
