Right‐sided ablation protocol
INFILTRATION
After the infiltration of the local anesthetic, right femoral vein access was achieved using ultrasound guidance. A 4‐mm nonirrigated tip ablation catheter was advanced to the region of the compact AV node, at the mid‐septal region, proximal and inferior to the His‐bundle recording position (Figure Intracardiac electrogram recordings (A) from the radiofrequency ablation catheter illustrating His potential (arrows) and fluoroscopy location (the mid‐septal region, proximal and inferior to the His bundle) in the posterior–anterior view (B) during right‐sided anterograde ablation.
