Torsades de Pointes (TdP) is a heart condition that is caused by a change in the electrical activity in the heart causing it to beat abnormally. TdP is a specific type of electrical activity that particularly affects the ventricles (the larger chambers in the heart), causing them to contract too quickly.

drug-induced torsades de pointes in women, who have longer QT intervals in the absence of drug therapy. The risk of torsades de pointes probably also varies with the type of drug irrespective of the effect on the QT interval. The absolute risk of torsades de pointes for sotalol and quinidine (Kinidine) appear higher than those associ-

Torsades de pointes (TdP) is a specific form of polymorphic ventricular tachycardia occurring in the context of QT prolongation; it has a characteristic morphology in which the QRS complexes “twist” around the isoelectric line. 83 rows 2021-04-03 In some serious cases, Torsades de pointes can precipitate unconsciousness (passing out), a condition known as syncope. Causes. There are several known Torsades de pointes causes. TdP can develop as a complication of QT syndrome, an uncommon condition where the gap between the Q and T wave in the heart is abnormally long. Torsades de pointes (TdP) is a potentially life-threatening arrhythmia associated with not only antiarrhythmic drugs, but noncardiac drugs of many different classes. All these drugs prolong the QT interval by their blocking of the potassium channel I(Kr), and many are metabolized by the cytochrome P … Torsades de pointes is a serious, and can be a life-threatening arrhythmia.

Oct 20, 2017 This prolongation reflects the delayed ventricular repolarization and is a cause of subsequent TdP. In addition to in vivo animal tests using canine 

2020-06-02 More commonly, torsades de pointes ventricular tachycardia (VT) results from a drug, usually a class Ia, Ic, or III antiarrhythmic drug. Other drugs that can induce torsades de pointes VT include tricyclic antidepressants, phenothiazines, and certain antivirals and antifungals (see CredibleMeds for an up-to-date list).

Drug-induced torsades de pointes is known to majorly strike the female population. Cause: Torsades de pointes can either be acquired or congenital in nature. Various factors such as drugs, underlying disease conditions and liver or renal failure can also lead to development of …

The risk of torsades de pointes probably also varies with the type of drug irrespective of the effect on the QT interval. The absolute risk of torsades de pointes for sotalol and quinidine (Kinidine) appear higher than those associ- Polymorphic ventricular tachycardia. Defined as ventricular tachycardia with varying QRS amplitude.
