Vectorcardiographic evaluation of ventricular repolarization in healthy individuals and LQTS mutation carriers

Abstract

Ventricular arrhythmia is a well-known cause of syncopal attacks and sudden cardiac death in humans. Ventricular repolarization (VR) is the most unstable phase in cardiac electrical activity and its regulation depends on the coordinated activity in multiple ion channels. Several physiological factors such as heart rate (HR), autonomic nervous system (ANS… (More)
