Abstract :Aim: Tp-e and Tp-e/QT are novel markers of ventricular repolarization. However, preexcitation in Wolff Parkinson White insert ignore into journalissuearticles values(WPW); syndrome may preclude accurate measurement of repolarization as assessed by the QT. We aimed to research the assessment of Tp-e and Tp-e/JT before and after ablation in WPW. Material and Method: We enrolled 50 consecutive patients with symptomatic WPW syndrome who underwent catheter ablation of their accessory pathways for treatment. All of the patients were successfully ablated. ECGs were performed before the procedure and repeated after the ablation procedure. Results: Tp-e insert ignore into journalissuearticles values(86.6±16.2 vs 80.6±12.5; p=0.021); and Tp-einsert ignore into journalissuearticles values(c); insert ignore into journalissuearticles values(96.7±18.9 vs 88.3±11.2; p=0,005); showed a significant decrease after the procedure. Tp-e/JT insert ignore into journalissuearticles values(0.307±0.053 vs 0.279±0.040; p=0.001); and Tp-e/JTinsert ignore into journalissuearticles values(c); insert ignore into journalissuearticles values(0.276±0.048 vs 0.255±0.045; p=0.009); showed a significant decrease after the procedure. There was a significant association between ERP and before procedure Tp-e insert ignore into journalissuearticles values(c); insert ignore into journalissuearticles values(r=- 0.370, p=0.008); and Tp-e/JT insert ignore into journalissuearticles values(r=- 0.371, p=0.008);. Conclusion: This study demonstrated that Tp-e and Tp-e/JT were significantly diminished in WPW after the ablation.
