TARIFA BALDIVIEZO, William; EFFEN AGUILAR, Gloria  e  CANDIA CAMPOS, Omar. FASCICULAR LEFT VENTRICULAR TACHYCARDIA BY ABNORMAL AUTOMATISM. Rev. Méd. La Paz [online]. 2014, vol.20, n.1, pp.40-43. ISSN 1726-8958.

We present the case of a male patient 32 years old with a ventricular tachycardia with image of right bundle branch block and superior axis, without hemodynamic compromise or structural heart disease in which pharmacological cardioversion with amiodarone and adenosine was attempted, afterwards electrical cardioversion that only decreased the tachycardia frequency without changing the morphology subsequently accelerating it. Finally verapamil was administered so that its reversion to sinus rhythm was achieved. He underwent electrophysiological study without being able to produce the tachycardia with atrial and ventricular overdrive associated with isoproterenol. By characteristics we conclude that it's an inferior left fascicular tachycardia whose mechanism is abnormal automatism with response to verapamil and possibly associated with physical exertion.
