Recurrent torsade de pointes type ventricular tachycardia in intracranial hemorrhage.
Two out of 72 cases of intracranial hemorrhage-induced polymorphous ventricular tachycardia with typical Torsade de Pointes morphology are presented. Both patients had marked QTc prolongation more than 550 ms. In one patient (QTc: 669 ms) Torsade de Pointes degenerated into fatal ventricular fibrillation. Even though polymorphous Torsade de Pointes type ventricular tachycardia is rare during the clinical course of intracranial hemorrhage, attention should be given to the QT interval. QTc prolongation more than 550 ms may carry a high risk of Torsade de Pointes type ventricular tachycardia and ventricular fibrillation.
