Fig. 2From: Modern physiological approach to inappropriate ICD shocks due to atrial fibrillation with very fast ventricular response. A case report(a) 12-lead ECG (at 25 mm/sec sweep speed) and intracardiac electrogram recorded from the lead tip showing the moment of AVN ablation (black arrow) (b) Posteroanterior X-ray image showing the successful ablation site at a safe distance from the LBB pacing lead tip (white arrow) (c) Final 12-lead ECG (at 25 mm/sec sweep speed) depicting regular and narrow QRS complexes.
