Anatomical Ablation Strategy for Noninducible Fascicular Tachycardia

Publication date: Available online 8 January 2016 Source:Cardiac Electrophysiology Clinics Author(s): Ahmed Karim Talib, Akihiko NogamiTeaser The presence of structural heart disease does not exclude fascicular ventricular tachycardia (VT), especially if the VT is verapamil sensitive. An empirical anatomic approach is effective when fascicular VT is noninducible or if diastolic Purkinje potential (P1) cannot be recorded during VT mapping. Pace mapping at the successful ablation site is usually not effective because selective pacing of P1 is difficult and there is an antidromic activation of the proximal P1 potential.
