A system and method for monitoring electrical dispersion of the heart is provided including
an implantable medical device and associated electrode system for sensing cardiac signals …

Ventricular repolarization and its manifestation in the T wave of the electrocardiogram have
long been a focus of clinical and experimental electrocardiology. In this short article, we …

Introduction: The occurrence of significant spatial dispersion of repolarization in vivo as it
relates to the mechanism of arrhythmia formation in the long QT syndrome (LQTS) continues …

The rate of repolarization (R Repol) and so the duration of the cardiac action potential are
determined by the balance of inward and outward currents across the cardiac membrane …

An implantable cardiac Stimulation device provides long QT interval therapy for preventing
abnormal ventricular activa tion-recovery time and ultimately ventricular arrhythmias. The …

BACKGROUND: Previous studies have showed that the interval between the peak and the
end of the T wave (Tp-e) is a marker of transmural dispersion of ventricular repolarization …

Beta-blockade is widely reported to reduce the incidence of syncope in 75–80% of patients
with congenital long QT syndrome (LQTS). However, despite full-doseβ-blockade, 20–25 …

Objectives: We sought to identify the triggers of ventricular tachyarrhythmia (VTA) in
experimental models of long QT type 2 (LQT2) and long QT type 3 (LQT3) syndromes …

Background The duration of ventricular repolarization (VR) and its spatial and temporal
heterogeneity are central elements in arrhythmogenesis. We studied the adaptation of VR …

Aims The effects of adrenergic activity and beta-blockade were studied in a canine
experimental model of type-3 long QT syndrome (LQT3) induced by application of …
