The T peak - T end interval is a parameter in the ECG that can show the dispersion pattern of ventricular repolarization. Prolonged repolarization dispersion is known to be a risk factor for ventricular arrhythmias through the mechanism of reentrant arrhythmogenesis. Thus, the T peak – T end interval can be used to detect ventricular repolarization abnormalities and as a marker in the ECG, wh…
