Ventricular repolarization analysis shows potential for arrhythmic risk stratification across various clinical settings.
This review summarizes traditional and dynamic methods for analyzing ventricular repolarization and their prognostic significance for arrhythmic risk stratification.
May refine arrhythmic risk stratification; leaves open prospective validation before clinical adoption.
Ventricular repolarization is a complex electrical phenomenon which represents a crucial stage in electrical cardiac activity. It is expressed on the surface electrocardiogram by the interval between the start of the QRS complex and the end of the T wave or U wave (QT). Several physiological, pathological and iatrogenic factors can influence ventricular repolarization. It has been demonstrated that small perturbations in this process can be a potential trigger of malignant arrhythmias, therefore the analysis of ventricular repolarization represents an interesting tool to implement risk stratification of arrhythmic events in different clinical settings. The aim of this review is to critically revise the traditional methods of static analysis of ventricular repolarization as well as those for dynamic evaluation, their prognostic significance and the possible application in daily clinical practice.
