Özet
Right ventricular outflow tract tachycardias comprise a subgroup of idiopathic ventricular tachycardias that occur in the absence of structural heart disease. Twelve-lead surface electrocardiography shows a left bundle branch block morphology and an inferiorly-oriented frontal axis during tachycardia. Non-sustained nature of arrhythmia and structure of the outflow tract makes catheter ablation of focal arrhythmia origin difficult. Herein, we presented ablation of right ventricular outflow tract tachycardia in a 32-year-old male patient using a new, simplified technique, described by Saleem et al., for three-dimensional mapping of the outflow tract. The patient was admitted with tachycardia of left bundle branch block with inferior axis morphology. In this technique, a spiral multipolar catheter was positioned in the right ventricular outflow tract and served as a guide for mapping and ablation. The patient was asymptomatic in the first and third months of the procedure.
