Key result
IV orciprenaline or overdrive pacing resolves TdP in a subarachnoid hemorrhage case by shortening Q-T.
Why the study?
Extreme Q-T prolongation and torsades de pointes in patients with subarachnoid hemorrhage require effective management strategies, but optimal treatment approaches are unclear.
Does intravenous orciprenaline or overdrive ventricular pacing control torsades de pointes in a patient with subarachnoid hemorrhage?

Does intravenous orciprenaline or overdrive ventricular pacing control torsades de pointes in a patient with subarachnoid hemorrhage?
In a patient with subarachnoid hemorrhage and torsades de pointes, shortening the Q-T interval with orciprenaline or overdrive pacing was effective when standard antiarrhythmics failed.
May control refractory torsades in subarachnoid hemorrhage via QT shortening; leaves open generalizability beyond this single case.
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.

Hust et al. (1984) conducted a case report in Subarachnoid hemorrhage with Q-T prolongation and torsades de pointes (n=1). Intravenous orciprenaline or overdrive ventricular pacing vs. Lidocaine, metoprolol, and atropine was evaluated on Control of arrhythmia. Shortening the Q-T interval by intravenous administration of orciprenaline or overdrive ventricular pacing successfully controlled torsades de pointes in a patient with subarachnoid hemorrhage.
