Corrected QT Interval Changes With Atypical Antipsychotics

Journal of the American Academy of Child & Adolescent Psychiatry, 2015
n this issue of the Journal, the meta-regression analyses by Jensen et al. aim to quantify the effects of antipsychotic I drugs on cardiac QT prolongation in the setting of pediatric randomized or open clinical trials. The common prescription of atypical antipsychotic medication, the known metabolic burden of these agents, and the theoretical potential

Rate-corrected QT interval: Techniques and limitations

The American Journal of Cardiology, 1993
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 many physiologic and pathologic factors that contribute to the QT interval, heart rate plays a major role.

QT Interval Correction in Patients with Cirrhosis

Journal of Cardiovascular Electrophysiology, 2006
Introduction: QT interval prolongation is a common electrophysiological abnormality in patients with cirrhosis. As QT interval varies with the heart rate, many QT correction formulas have been proposed, the Bazett's one being the most criticized because it overcorrects the QT interval and may be misleading. This study focused on the QT‐RR relationship

Fast and spurious: Correcting the QT interval

Heart Rhythm, 2016
In an era of immense technological advance, the resting ECG remains at the cornerstone of investigations for the evaluation and treatment of cardiovascular patients. In particular, the QT-interval duration has long been a metric of risk in focused areas such as mendelian long QT syndrome and in broader fields such as antiarrhythmic drug efficacy and ...

Influence of Spinal Anesthesia on Corrected QT Interval

Regional Anesthesia and Pain Medicine, 2005
Prolongation of the QT interval may result in grave cardiac arrhythmias, polymorphic ventricular tachycardia ("torsades de pointes"), and ventricular fibrillation. We assessed the influence of spinal anesthesia on the QTc interval and the potential arrhythmogenicity of this method of anesthesia.Assessment was performed in 20 male unpremedicated ...
