AbstractTorsade de pointes (TdP) is a life-threatening polymorphic ventricular tachycardia that is related to QT prolongation. Although QT prolongation is commonly seen in acute stroke, TdP is rare. We report the case of a 78-year-old woman with ischemic stroke who presented with TdP as the initial manifestation of early neurologic deterioration. We hypothesized that an increase in intracranial pressure may result in neurohormonal activation, QT prolongation, and then myocardial damage, leading to TdP. We highlight that new onset of TdP in a patient with stroke may reflect neurologic deterioration, requiring further evaluation and specific intervention.
