Abstract

The case of a 74-year-old patient who experienced an electrical storm while being admitted to the intensive unit for acute hypercapnic respiratory failure. The patient had a history of atrial fibrillation and is on dofetilide. The electrical storm was characterized by multiple runs of polymorphic ventricular tachycardia, which was believed to be secondary to the use of dofetilide and later the usage of amiodarone. The patient was treated with lidocaine infusion, ICD reprogramming, and intravenous magnesium sulfate, which resulted in the successful termination of the tachycardia. This case highlights the necessary steps in the management of an electrical storm, the possible pro-arrhythmogenic effects of anti-arrhythmia medications, and the relative frequency of electrical storms in ICD recipients.
