Reliable information on the proper use of QT-prolonging medications is scarce. 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 ...
Among the factors that could predispose to torsades de pointes, hypokalemia and hypomagnesemia are particularly significant and remediable. Physicians should monitor potassium and magnesium levels in patients who start antiarrhythmic QT-prolonging medications and supplement them as needed, especially in patient...
cessation of all QT-prolonging medications Evidence regarding which drugs cause torsades is extremely murky. In some cases it seems that drugs have been incorrectly maligned (e.g. azithromycin, olanzapine). Which drugs prolong QT the most?
