Overdrive Pacing for Persistent Torsades de Pointes and Pulseless Ventricular Tachycardia.

Abstract

A 53-year-old presented to the emergency department following a fall and was found to have recurrent episodes of torsades de pointes and pulseless ventricular tachycardia on cardiac monitoring. He had been abusing nimetazepam for sleep issues over the preceding one month. Despite correction of electrolytes, the arrhythmias were persistent which necessitated temporary overdrive pacing. The patient made an uneventful recovery and the temporary pacing was successfully removed with no recurrence of the malignant arrhythmias prior to discharge.
