RADIOFREQUENCY CATHETER ABLATION OF AV NODAL REENTRANT TACHYCARDIA INSCIMITAR SYNDROME

A 70-year-old male is described who suffered from daily episodes of su praventricular tachycardia that was refractory to oral medical treatme nt since adolescence. Electrocardiographical and electrophysiological evaluation confirmed atrioventricular nodal re-entrant tachycardia (AV NRT). This arrhythmia commonly occurs in patients without concomitant heart disease. However, in this patient a variant form of the scimitar syndrome was found by coincidence at the age of 56 years. This report describes (1) the variant form of the scimitar syndrome, (2) the coex istence of AVNRT in scimitar syndrome, and (3) the feasibility of radi ofrequency catheter ablation of AVNRT in the presence of this congenit al anomaly.
