QT dispersion was originally proposed to measure spatial dispersion of ventricular recovery
times. Later, it was shown that QT dispersion does not directly reflect the dispersion of …

Background—Both a prolonged QT interval and increased QT interval dispersion (QTD)
have been proposed as surface ECG markers of vulnerability to ventricular arrhythmias and …

Characteristics of the M Cell. The discovery and characterization of the M cell, a unique cell
type residing in the deep layers of the ventricular myocardium, has opened a new door in …

QT dispersion (QTD) on 12-lead ECGs has been proposed as a marker of malignant
ventricular tachyarrhythmias, and increased QTD has been reported in long QT syndrome …

Malignant cardiac arrhythmias which result in sudden cardiac death may be present in
individuals apparently healthy or be associated with other medical conditions. The way to …

The congenital long-QT syndrome (LQTS) is characterized by prolonged QT intervals, QT
interval lability, and polymorphic ventricular tachycardia. The manifestations of the disease …

Background—This study examines the cellular basis for the phenotypic appearance of
broad-based T waves, increased transmural dispersion of repolarization (TDR), and torsade …

It is becoming clear that mutations in the KVLQT1, human “ether-a-go-go” related gene,
cardiac voltage-dependent sodium channel gene, minK and MiRP1 genes, respectively, are …
