Ultrasound guided left interscalene block for the treatment of refractory electrical storm

Electrical storm (ES) is a life-threatening medical emergency and is often associated with a poor outcome [1]. The condition is defined as 3 or more sustained episodes of ventricular tachycardia, ventricular fibrillation, or appropriate shocks from an implantable-cardioverter-defibrillator (ICD) within 24h [1]. Sympathetic blocks have been beneficial in stopping or decreasing ES and consequently improving 1-week mortality [2]. Temporary sympathetic blockade can be accomplished by blocking the cervical sympathetic ganglion, in the periphery at the adrenergic receptor, or in the thoracic central neuraxis [2,3].
