Assessment of ventricular repolarization alterations in subjects with early repolarization
Although the electrocardiographic (ECG) features of early repolarization (ER) have been studied extensively, no systematic quantification of ventricular repolarization in subjects with ER has been conducted so far.The objective of the present study was to evaluate ECG and spatial vectorcardiographic (VCG) descriptors of ventricular repolarization in ER

Dispersion of ventricular repolarization in dilated cardiomyopathy [PDF]
Increased dispersion of ventricular repolarization has been shown to be a marker for increased risk of ventricular tachyarrhythmias in various cardiac disorders. The present study is aimed at comparing the values of four dispersion indices in four clinical groups: normal subjects (n = 23), patients with intraventricular conduction defects (QRS > 0.12 s)

The apicobasal dispersion of ventricular repolarization in humans is associated with age and affects arrhythmia vulnerability. [PDF]
Abstract figure legend We investigated the age‐ and sex‐related differences in the apicobasal repolarization gradient (ABRG) and evaluated their possible role inventricular arrhythmia vulnerability. Electrocardiographic imaging (ECGI) was performed in healthy subjects during sinus rhythm, and the average recovery time (RT) and activation–recovery ...

Adaptation of ventricular repolarization to heart rate change in humans [PDF]
Background: Life-threatening cardiac rhythm disturbances and sudden death are common manifestations of heart disease. Disturbances in electrical recovery (ventricular repolarization; VR) are important mechanisms behind ventricular arrhythmias, which ...

Malignant early repolarization as cause of sudden death has taken on great importance in recent years. It has been described as an entity capable of producing ventricular arrhythmic events, causing from episodes of syncope to sudden cardiac death ...

High risk of ventricular repolarization abnormalities among hemodialytic end-stage renal disease patients [PDF]
Introduction: Patients with chronic renal disease (CKD) are at a significantly elevated risk for ventricular arrhythmia. Several electrocardiographic (ECG) methods can be used to assess the ventricular arrhythmia risk on the standard 12-lead ECG.Aim ...

Dispersion of Ventricular Repolarization [PDF]
The QT interval is considered to be a surrogate of cellular action potential duration. However, it yields a limited view of the complex electrogenesis of the ventricular repolarization (VR). Evidence of T-wave end inequality among surface ECG traces back to Wilson et al,1 and it was recently revived by the concept of dispersion.2 Because of its ...

Increased vulnerability of human ventricle to re-entrant excitation in hERG-linked variant 1 short QT syndrome [PDF]
The short QT syndrome (SQTS) is a genetically heterogeneous condition characterized by abbreviated QT intervals and an increased susceptibility to arrhythmia and sudden death.
