  • Title: Measurement of T wave variability in body surface ECG.
    Author: Baumert M.
    Journal: J Electrocardiol; 2016; 49(6):883-886. PubMed ID: 27539161.
    Abstract:
    Lability in the ventricular repolarization process has been associated with an increased risk of experiencing ventricular tachycardia or fibrillation. A number of risk predictors have been devised that quantify beat-to-beat variability in the T wave morphology of body surface ECG. Initial studies have suggested that measurement of T wave variability may yield important prognostics markers of cardiac mortality, but approaches and experimental designs vary. The aim of this contribution is to provide an overview of existing techniques as well as discuss some of the methodical considerations.
