Po-665-02 noninvasive cardiac mapping during sinus rhythm identifies targets for successful catheter ablation of ventricular tachycardia

Accurate and expedited identification of scar regions most prone to reentry helps guide ventricular tachycardia (VT) ablation. Several methods for catheter mapping in sinus rhythm have been studied, including isochronal late activation mapping (ILAM) and deceleration zones (DZ). Noninvasive electrocardiographic imaging (ECGI) of sinus rhythm may identify these areas before the procedure.
