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 …

The duration of the QT interval on the surface electrocardiogram represents the time
required for all ventricular depolarization and repolarization processes to occur. Among the …

Background—Increased QTc dispersion has been associated with an increased risk for
ventricular arrhythmias and cardiac death in selected patient populations. We examined the …

Ventricular tachyarrhythmias can be danger-ous. They may result from cardiovascular
disease, principally ischaemic heart disease, or they may be an unwanted effect of drug …

OBJECTIVES.: This study tested the correlation of QT and JT dispersion and other
potentially useful electrocardiographic (ECG) indexes with dispersion of repolarization and …

OBJECTIVES.: The aim of this study was to estimate the value of QT dispersion
measurement from the standard 12-lead electrocardiogram (ECG) in identifying patients …

The clinical course of 'Takotsubo'cardiomyopathy closely resembles that of acute myocardial
infarction (AMI) and coronary angiography (CAG) is usually performed to distinguish the 2 …

Cardiovascular death is the most important cause of mortality in alcoholics, yet alcohol may
protect against ischaemic heart disease. This could be explained if deaths were a …

OBJECTIVE--To evaluate changes in QT dispersion and components of the QT interval in
patients admitted with unstable angina and acute myocardial infarction and to study the …

QT Dispersion. QT dispersion is defined as the difference in QT interval between the
different leads of the surface 12‐lead ECG. This may provide an indirect measure of the …
