Abstract/OtherAbstract:
Verapamil-sensitive fascicular ventricular tachycardia (VT) of right bundle branch block (RBBB) and superior axis pattern is typically seen in young patients with structurally normal hearts and considered "idiopathic". Recently, involvement of the Purkinje system in post-infarction monomorphic VT that mimics such idiopathic fascicular VT has been described. In this report we describe a case of a patient who following myocardial infarction developed left posterior fascicular Purkinje reentrant VT that was sensitive to verapamil. The VT was successfully treated by radiofrequency ablation guided by three dimensional electroanatomical CARTO mapping. Our case highlights that involvement of Purkinje fibers should be considered in post infarction patients with VT of narrow QRS duration, RBBB morphology and superior axis. Recognition of such VT is clinically important, as this arrhythmia is amenable to curative catheter ablation.
