Figure shows diastolic fractioned low-amplitude electrogram registered from the distal dipole of the ablation catheter (EPI) during sinus rhythm and a premature ventricular complex at the successful ablation location. The morphology of the second complex suggests an infero-lateral origin of ventricular activation and the pattern is of an epicardial origin because of pseudo delta wave (Δ) and the prolonged intrinsicoid deflection in V2 (ID).
