Résumé
A 35-year-old woman was referred for treatment of a supraventricular tachycardia. The tachycardia was diagnosed as a slow-fast form of atrioventricular nodal reentrant tachycardia. Radiofrequency ablation targeting the antegrade slow pathway was performed at the posterior septum of the right atrium. After the radiofrequency ablation, ventricular extrastimulus pacing was performed to assess the retrograde slow pathway, which was suggested before the ablation. The prolongation of the VA interval with a 10 ms decrease in the S2 pacing interval was 60 ms and retrograde dual pathways were suspected. However, the HA interval did not change and a prolongation of the VA interval was caused by the prolongation of the VH interval and no additional ablation was required.
