title: [QTc interval prolongation and polymorphic ventricular tachycardia related to subarachnoid hemorrhage].
abstract: A 55-yr-old woman was taken to the hospital after recovering from a presyncopal episode. The electrocardiogram showed sinus bradycardia with QTc interval of 840 msec. Few minutes later, the patient developed a polymorphic ventricular tachycardia and subsequent cardiac arrest requiring cardiopulmonary resuscitation. A week later she presented with severe headache, seizures and decerebrate movements. Cranial computed tomography scan showed subarachnoid hemorrhage with intracranial hypertension requiring decompressive craniectomy. On the follow- up the electrocardiograms always showed prolonged QTc interval, without any new arrhythmic event. The patient's clinical course was unfavorable and required maximum dose of vasoactive drugs. She died 13 days after admission.
