Hachiya et al used the Peak Deflection Index (PDI) to identify a patient with outflow tract ventricular tachycardia who is unlikely to respond to radiofrequency catheter ablation (RFCA). These patients may have the origin of the tachycardia at a point not affected by the catheter ablation, either deep within the ventricular septum or at an epicardial site.
