Amaç Koroner arter bypas greftleme sonrası ventriküler eksra atımdan süreğen olmayan venrtiküler takikardi, süreğen venrtiküler takikardi ve ventriküler fibrilasyon gibi takiaritmilere değişen aritmik tablolar görülebilir. Bu çalışmada atan kalpte ve on pump Koroner arter bypas greftlemenin QT dispersiyonu üzerine olan etkilerini araştırmayı amaçladık.Materyal ve Metot: Çalışmaya 64 koroner arter bypas greftleme adayı olan hasta alındı. Bu hastalar on-pump koroner arter bypas greftleme grubu (n= 40) ve atan kalpte koroner arter bypas greftleme grubu (n= 24) olarak iki gruba ayrıldı. Elektrokardiyografi  ve ekokardiyografi, cerrahiden önce ve 1 ay sonrasında uygulandı.Bulgular: Her iki grubunun bazal karekteristik özelliklerine bakıldığında, gruplar arasında istatistiksel açıdan fark saptanmadı. Her iki koroner arter bypas greftleme tekniğinin kendi içerisinde operasyon öncesi ve sonrasında anlamlı değişiklik mevcuttu. Operasyon sonrası atan kalpte koroner arter bypas greftleme ve pompada koroner arter bypas greftleme gruplarının  minimum QT, maksimum QT, QT dispersiyonu, minimum QTc, maksimum QTc ve  QTc dispersiyonu açısından karşılaştırıldığında aralarında istatiksel açıdan anlamlı fark yoktu.Sonuç: Bizim çalışmamızda her iki koroner arter bypas greftleme tekniğinin de QT dispersiyonu üzerine düzeltici etkisi olduğu gözlenmiştir. Fakat iki tekniğin birbirlerine üstünlüğü olmadığı görülmüştür.
