Torsade de pointes is an uncommon and distinctive form of polymorphic ventricular tachycardia (VT) characterized by a gradual change in the amplitude and twisting of the QRS complexes around the Torsade de Pointes (TdP) is a life-threatening arrhythmia closely linked to abnormal cardiac repolarization. It has been demonstrated that cardiac ion channel alterations underlying cellular repolarization results in the phenotypic expression of long QT syndrome, which is closely associated with TdP. However, the mechanisms by which prolonged repolarization leads to TdP remain controversial.
