A Challenging Case of Electrical Storm in an Implantable Cardioverter Defibrillator Patient.

ABSTRACT

Implantable cardioverter defibrillators (ICD) have become indispensable in managing life-threatening ventricular arrhythmias. On average, 50%-70% of the patients receive a device-based therapy within the first two years post implantation. A few patients experience the electrical storm (ES). ES is a syndrome of recurrent ventricular tachycardia or fibrillation occurring two or more times in a 24-hour period, calling for the need of electrical cardioversion or defibrillation to stabilize the patient. We present the case of a patient with severe cardiomyopathy who presented with resistant ES after failing to respond initially to conventional medications like amiodarone and lidocaine. Propofol infusion was not an option due to his severe cardiomyopathy and hypotensive shock state. Aggressive treatment with intravenous medications stabilized his ES and he was eventually transferred to an outside facility for ventricular tachycardia ablation.
