Although a QT interval of at least 500 milliseconds generally has been shown to correlate with a higher risk of torsades de pointes, there is no established threshold below which prolongation of the QT interval is considered free of proarrhythmic risk. The risk of torsades de pointes should be...
Cardiac arrest due to torsades de pointes (TdP) is an uncommon but potentially catastrophic event associated with QT interval-prolonging drugs [ 1 ]. Numerous medications that may cause TdP are available for use in clinical practice, and include drugs for management of cardiovascular diseases, prima...
