Q-T prolongation and torsades de pointes in a patient with subarachnoid hemorrhage

An extreme Q-T prolongation in a patient with subarachnoid hemorrhage was observed. Multiple torsades de pointes occurred. Lidocaine, metoprolol, and atropine were not effective in controlling the arrhythmia, whereas shortening the Q-T interval by intravenous administration of orciprenaline or overdrive ventricular pacing was successful. The occurrence of T wave alternations was a sign of increased sympathetic activity.
