The Relationship between Tpeak-end Interval Duration and Tpeak-end/QT Ratio, and Arrhythmias in Patients with Coronary Slow Flow

Abstract

Background: Coronary Slow Flow (CSF) is described as delayed opacification of the distal vasculature and angiographically Normal Coronary Arteries (NCA). Numerous studies have suggested that the interval from the peak to the end of electrocardiographic T wave (Tp-e) may correspond to transmural dispersion of repolarization and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias.
