Use of sympathomimetic nasal spray in association with cardiac fibroma: an unusual cause of ventricular tachycardia.

A patient prescribed oxymetazoline hydrochloride nasal drops presented with recurrent ventricular tachycardia of fascicular origin. Cardiac ultrasound showed a calcified lesion, presumably a fibroma arising from the interventricular septum. Fascicular tachycardia related to the lesion and provoked by the use of a sympathomimetic agent is postulated.
