A 75-year-old man presented with dizziness and fatigue secondary to ventricular and supraventricular arrhythmias. He underwent an elective ablation but continued to suffer from ventricular tachycardia with cardiovascular instability despite antiarrhythmic therapy with multiple agents. The patient continued to develop episodes of ventricular tachycardia and an episode of ventricular fibrillation. Electrical storm encompasses a situation of cardiac instability which may present as several episodes of ventricular tachycardia or ventricular fibrillation in a short period. We performed an ultrasound-guided left stellate ganglion block at the bedside which resulted in abolition of electrical storm. The patient demonstrated sinus rhythm with episodes of sinus tachycardia. Left stellate ganglion block has proven to be a successful mode of treatment for those patients with ventricular tachyarrhythmia resistant to medical management or those who fail atrioventricular node ablation. Ultrasound-guided left stellate ganglion block is a valuable and effective means to providing sympathectomy in the management of electrical storm or ventricular tachyarrhythmias.
