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. Although Torsades de pointes may resolve spontaneously, it can also lead to ventricular fibrillation and death.
