Amaç: Bu çalışmanın temel amacı N-asetil sistein'in (NAS) supraventriküler taşikardi ablasyonundan sonra atriyal efektif refrakter periyod (AERP) üzerine ve klinik takipte orijinal aritmi nüksü ve AF gelişme sıklığı üzerine etkisini araştırmaktır. Metod: Nisan 2007-Eylül 2008 tarihleri arasında SVT nedeni ile ablasyon yapılan ardışık 21 hasta çalışmaya alındı. Hastalar ablasyon işleminden sonra plasebo ve NAS gruplarına randomize edildiler. Ve iki siklüs uzunluğunda AERP ve atriyoventriküler nod efektif refrakter periyod (ANERP) ölçüldü. NAS`ın AERP üzerine olan etkisi değerlendirildi. Hastalar hastaneden çıktıktan sonra NAS`ın, orijinal SVT`nin nüksü ve AF gelişme sıklığı üzerine etkileri değerlendirmek için hastalara 24 saatlik holter takıldı. Bulgular: İki siklus uzunluğunda ölçülen ANERP [600 ms'de (254 ± 52'ye 360 ± 150, p=0.181), 400 ms'de (293 ± 50'ye 256 ± 78, p=0.494)] ve AERP [600 ms'de (236±58'e 218±63, p=0.602), 400 ms'de (215± 17'ye 229± 41, p=0.526)] NAS grubunda ve kontrol grubunda benzer bulundu.Sonuç: NAS'ın AERP üzerine bir etkisi tespit edilememiştir.Anahtar kelimeler: N-asetil sistein, atriyal efektif refrakter periyod, atriyoventriküler nod efektif refrakter periyodAbstractThe effects of N-acetylcysteine on shortening of the atrial effective refractory period and recurrence of original arrhythmia and atrial fibrillation in clinical follow-up after ablation of supraventricular arrhythmias.Objective: The aim of the present study was to evaluate the effects of antioxidant agent N-acetylcysteine (NAC) on shortening of the atrial effective refractory period and recurrence of original arrhythmia and atrial fibrillation in clinical follow-up after ablation of supraventricular arrhythmias. Method: Twenty one consecutive patients meeting study inclusion criteria who have undergone ablation of supraventricular arrhythmias between April 2007 and September 2008, were participated in this study. All the patients were randomized to NAC group or placebo after ablation. AERP and atrioventricular nodal effective refractory period (ANERP) was measured at two cycle length. The effect of NAC on AERP evaluated. After patients leave the hospital, the 24-hour Holter recording was performed and recordings were analyzed for recurrence of supraventricular arrhythmias and atrial fibrillation. Results: There was no significant difference in ANERP [600 ms (254 ± 52 vs. 360 ± 150, p=0.181), 400 ms (293 ± 50 vs. 256 ± 78, p=0.494)] and AERP [600 ms (236±58 vs. 218±63, p=0.602), 400 ms (215± 17 vs. 229± 41, p=0.526)] was documented at two cycle lengths between NAS group and placebo.Conclusion: There was no effect of NAC on shortening of the AERP.Key words: N-acetylcysteine, atrial effective refractory period, atrioventricular nodal effective refractory period
