Relationship between QT interval and ventricular electrical axis: A new suggestion for Lead selection in QT interval measurement [PDF]
Acta Medica Iranica, 2000 Exploration of the interlead QT variation (QT dispersion) introduced cardiologists to some new concepts including the deed to define a standard for lead selection in the measurement of QT interval and the reason or factors contributing to QT dispersion ...

Is there a utility for QRS dispersion in clinical practice? [PDF]
, 2017 Prognostic markers derived from standard ECG have always been seductive. Increased dispersion of durations of the P wave, of the QRS complex, or of the QT interval has been associated with the risk of atrial fibrillation, ventricular arrhythmias, sudden ...

Effect of isolated coronary artery ectasia on dispersion of P-wave and QT interval
The Egyptian Heart Journal, 2012 Background: Coronary artery ectasia (CAE) is well-recognized, angiographic finding of abnormal coronary artery dilatation, and detected in 0.3–5.3% of angiographic studies.

ARRITMIAS VENTRICULARES Y NUEVO SÍNDROME CORONARIO AGUDO EN PACIENTES CON INFARTO Y DISPERSIÓN DEL INTERVALO QT PROLONGADO / Ventricular arrhythmias and new acute coronary syndrome in patients with infarction and prolonged QT dispersion [PDF]
CorSalud, 2013 Resumen Introducción y objetivos: La isquemia miocárdica aumenta la dispersión del intervalo QT del electrocardiograma, ya que en estas circunstancias la duración del potencial de acción disminuye en la zona del insulto isquémico, al crear una dispersión

Faraday rotation: effect of magnetic field reversals
, 2010 The standard formula for the rotation measure, RM, which determines the position angle, $\psi={\rm RM}\lambda^2$, due to Faraday rotation, includes contributions only from the portions of the ray path where the natural modes of the plasma are circularly ...
