Figure 2 Intracardiac echocardiographic long-axis image showing false tendon extending from septum toward posterior wall of left ventricle. Ablation catheter (gray arrows) is seen at the junction of the septum and false tendon. The false tendon is a single substrate with multiple exit sites, explaining the different morphologies of ventricular tachycardia having the same cycle length.

Figure 3 Surface ECG leads I, aVF, V1, and V6 and intracardiac signals. Arrows indicate presystolic potentials during successful site of ablation of LBBB with right axis morphology VT. Ablation catheter is located at the site of septal attachment of the false tendon. LBBB = left bundle branch block; MAPD = mapping catheter distal; MAPP = mapping catheter proximal; VT = ventricular tachycardia.
