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.
