摘要

A20-year-old male with a structurally normal heartunderwent catheter ablation (CA) for verapamilsensitiveventricular tachycardia (VT; Figure A).During VT, the left ventricle (LV) was mapped with a3.5-mm-tip linear quadripolar catheter (Thermocool SF,Biosense Webster, Diamond Bar, CA, USA). No lowvoltagearea was seen. The earliest activation occurred at thebasal anterolateral LV area with a tiny Purkinje potential(PP; 0.05mV), preceding the QRS by 35ms (Figure A). TheLV was then re-mapped with a 5-spline 1-mm electrode20-pole 2-6-2-mm spacing PentaRay catheter (BiosenseWebster), identifying an earlier (?51ms) distinct highamplitude(1.5mV) presystolic PP followed by fractionatedpotentials at the medial surface of the anterior papillarymuscle (APM) (Figure B). The entrainment study confirmedthis site as an exit of the VT (Supplementary Figure), andleft APM fascicular-Purkinje VT was diagnosed.1 RadiofrequencyCA was successful.
