Ventricular Tachycardia due to Long QT Syndrome Associated to Non-Cardiac Pharmacological Agents

چکیده
J Cardiol Curr Res 2016, 5(5): 00176 the declining inflow of sodium and calcium. These ion currents utilize specific channels that are under the influence of multiple factors. The long QT syndrome is characterized by QT interval prolongation and a tendency to develop a potentially lethal ventricular tachycardia [1,2]. Several anti-arrhythmic drugs, as well as some non-cardiac medications, block a specific potassium channel: IKr. In the case of the anti-arrhythmic drugs, inhibition of IKr channels is the mechanism for the drug’s therapeutic effect. Non-cardiac drugs that cause the long QT syndrome block these channels incidentally.

Drug-induced long QT syndrome and Torsade de Pointes.
Several medications, including drugs prescribed for noncardiac indications, have been associated with a prolongation of the QT interval on the surface electrocardiogram. Under certain circumstances, this clinical manifestation may reflect an increased risk for patients presenting with a polymorphic ventricular tachycardia known as torsade de pointes. Drugs that prolong the QT interval belong to...
متن کاملMonogenec Arrhythmic Syndromes: From Molecular and Genetic Aspects to Bedside
The abrupt cessation of effective cardiac function that is generally due to heart rhythm disorders can cause sudden and unexpected death at any age and is referred to as a syndrome called "sudden cardiac death" (SCD). Annually, about 400,000 cases of SCD occur in the United States alone. Less than 5% of the resuscitation techniques are effective. The prevalence of SCD in a population rises with...

Drug-induced long QT syndrome (LQTS) is characterized by prolongation of the QT interval and the risk of syncope and sudden cardiac death due to torsades de pointes (TdP) ventricular tachycardia upon exposure to certain antiarrhythmic and non-cardiovascular drug therapy. Most of the drugs responsible for LQTS can also block the rapid delayed rectifier K current, IKr in ventricular cardiomyocyte...
متن کاملPolymorphous ventricular tachycardia: clinical characterization, therapy, and the QT interval.
Forty-five consecutive patients with polymorphous ventricular tachycardia (PVT) were studied. The arrhythmia proved to be of a drug-related cause in 27 and due to an electrolyte disorder in four patients. Coexistent cardiac diseases without metabolic or drug-related abnormalities included ischemic heart disease in three, cardiomyopathy in three, and mitral valve prolapse in two. PVT was exercis...

Torsades de pointes (TdP) is defined as a polymorphic ventricular tachycardia (VT) with a twisting QRS morphology associated with a prolonged QT interval and/or increased U wave amplitude in the ECG.1,2 Patients with acquired or congenital long-QT syndrome (LQTS) can develop TdP that results in sudden cardiac death. Fifty or more drugs, both typical antiarrhythmic agents such as quinidine as we...
