Probable Quetiapine-Mediated Prolongation of the QT Interval
Journal of Pharmacy Practice, 2011 Purpose: QT prolongation can occur with both first- (FGA) and second-generation antipsychotics (SGA). QT prolongation was identified in an adult patient who presented to the emergency room with schizophrenia, fluid and electrolyte imbalances, and ...

Gatifloxacin and Prolonged QT Interval
The American Journal of the Medical Sciences, 2004We report the case of a 54-year-old woman who, while being treated for acute sinusitis with gatifloxacin, presented with syncope and was found to have a markedly prolonged QT interval. After stopping gatifloxacin, the QT interval normalized. We speculate that her episode of syncope was caused by a ventricular arrhythmia that resulted from an increased ...

Prolongation of the QT interval in primary aldosteronism
Clinical and Experimental Pharmacology and Physiology, 2005SUMMARY1. Only limited information is available concerning the changes in the electrocardiogram in primary aldosteronism. The aim of the present study was to determine factors influencing the QTc interval in patients with primary aldosteronism.2. Nineteen patients with primary aldosteronism caused by a Conn's adenoma and 69 patients with essential ...

Antipsychotic Drugs and QT Interval Prolongation
Psychiatric Quarterly, 2003The QTc prolongation by antipsychotic drugs is of major concern, especially in light of the data indicating an increased risk of sudden death in psychiatric patients taking these drugs. Sudden death in psychiatric patients could be partially attributed to drug-induced torsades de pointes and for this reason careful evaluation of QTc prolonging ...

Prolonged QT-Interval Syndromes
JAMA: The Journal of the American Medical Association, 1986PROLONGATION of the QT interval, either on a congenital or an acquired basis, is associated with an increased likelihood of malignant ventricular arrhythmias. 1-3 Patients with QT prolongation frequently develop recurrent attacks of syncope or may present with sudden death.

Prolonged QT interval and cocaine use
Journal of Electrocardiology, 1997Cardiovascular consequences of cocaine use are well known, and surveillance for them is common practice in the routine care of cocaine abusers. However, the cardiac electrical abnormalities that arise, although studied in animal experiments, lack correlation with human reports.

Tamoxifen-induced QT interval prolongation
Journal of Clinical Pharmacy and Therapeutics, 2008We report on a case of tamoxifen-induced QT interval prolongation in a 56-year-old-female patient with hormone-dependent carcinoma of the right breast, stage T2N0M0, grade 3 and HER-2 negative. Partial mastectomy with axillary lymph node excision was performed in July 2007 with adjuvant hormonal and radiation therapy.

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).

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.

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 ...
