Tachycardia originating from the fascicles or His-Purkinje 1 system includes a wide spectrum of arrhythmias such as ventricular fibrillation (VF) and ventricular tachycardia (VT) which could be monomorphic or polymorphic with various substrates, locations and mechanisms.1 The most common type of reentrant fascicular tachycardia is left posterior fascicular VT (LPF-VT) which was recognized as an electrocardiographic entity by Zipes et al.2 who defined its diagnostic triad as following: (1) induction with atrial pacing, (2) right bundle branch block (RBBB) and a left-axis configuration, and (3) manifestation in patients without structural heart disease. In 1981, Belhassen et al.3 reported verapamil sensitivity, as a fourth identifying feature of this tachycardia.
