1 HeartRhythm Case Reports
Catheter ablation of ventricular ectopy originating from the left fascicular conduction system triggering polymorphic ventricular tachycardia in Brugada syndrome  Jan Hluchy, MD, PhD, FESC, Magnus W. Prull, MD, Christian Berndt, MD, Bodo Brandts, MD  HeartRhythm Case Reports  DOI: /j.hrcr Copyright © 2019 Heart Rhythm Society Terms and Conditions

2 Figure 1 A: Polymorphic ventricular tachycardia associated with syncope. B: The challenge test (intravenous ajmaline 40 mg) revealing a diagnostic Brugada electrocardiogram with ventricular bigeminy.

3 Figure 2 A–C: Intracardiac recordings showing sinus and ventricular premature beats. D: Left anterior oblique (upper panel) and right anterior oblique (lower panel) radiographs of the ablation catheter (Abl) positioned at the successful ablation site. E: Pace mapping showing a nearly perfect pace map obtained from the successful ablation site. F: Intracardiac recording showing a prolonged fascicular potential-ventricular interval (PV) of 35 ms postablation. CS = coronary sinus; H/He = His bundle potential; HBE = His bundle electrogram; HIS = His bundle catheter; P/Pe = fascicular potential; RV = right ventricle; RVA = right ventricular apex.
