Electrocardiographic implications of the prolonged QT interval
The American Journal of Emergency Medicine, 2013The QT interval measures the time from the start of the QRS complex to the end of the T wave. Prolongation of the QT interval may lead to malignant ventricular tachydysrhythmias, including torsades de pointes. Causes of QT prolongation include congenital abnormalities of the sodium or potassium channel, electrolyte abnormalities, and medications ...

Aliskiren-Induced QT Interval Prolongation
Southern Medical Journal, 2009Aliskiren gained FDA approval for the treatment of hypertension in 2007. It is the first approved pharmaceutical to manage hypertension by direct renin inhibition. With the introduction of novel drugs and mechanisms of action comes the challenge of monitoring for new unreported adverse events.

Biventricular Pacing and QT Interval Prolongation
Journal of Cardiovascular Electrophysiology, 2007Introduction: The purpose of this study was to examine BiV pacing‐dependent changes in QT interval and the related potential for proarrhythmia. Biventricular (BiV) pacing has emerged as a promising therapy for patients with advanced congestive heart failure (CHF) and bundle branch block (BBB).

In response to the prolonged QT interval and use of the TpTe interval…
The American Journal of Emergency Medicine, 2013We thank you for your feedback and commentary regarding our original submission. In response to the questions regarding measurements of QTc, it is our practice to manually measure the QT interval in cases where we are concerned, and we typically use the Bazett formula for calculation of the QTc.

QT-Interval Prolongation Produced by Probucol
Archives of Internal Medicine, 1981To the Editor. —Probucol (4,4′-[(1-methylethylidene) bis (thio)] bis [2,6-bis(1,1-dimethylethyl) phenol]) is a recently introduced drug for the lowering of serum cholesterol levels in familial hypercholesterolemia type II. 1,2 Side effects are considered slight, and no ECG abnormalities have been reported in humans receiving probucol. 2,3 This article

Drug-Induced Prolongation of the QT Interval
New England Journal of Medicine, 2004The single most common cause of the withdrawal or restriction of the use of marketed drugs has been QT-interval prolongation associated with polymorphic ventricular tachycardia, or torsade de pointes, a condition that can be fatal. This review summarizes the current knowledge about molecular and clinical predictors of drug-induced QT-interval ...

Low-Energy Diets and Prolonged QT Intervals
JAMA: The Journal of the American Medical Association, 1987To the Editor.— In a recent review entitled "Prolonged QT-Interval Syndromes," 1 the author indicates that "prolongation of the QT interval, malignant ventricular arrhythmias, and unexpected sudden death have been reported in patients who have lost considerable weight on the very-low-energy liquid protein diets." Dr Moss states that "sustained use of ...
