Spiked helmet sign after percutaneous left stellate ganglion ablation in a patient with long QT syndrome

摘要

Abstract “Spiked helmet” is a type of ST elevation, which is generally observed in critically ill patients and associated with very poor prognosis. Here we present a case of previously undiagnosed long QT syndrome admitted with polymorphic ventricular tachycardia (PMVT) unresponsive to pharmacological treatment and developed “spiked helmet” sign after left percutaneous stellate ganglion ablation. Highlights ? Spiked helmet sign is related with very poor in hospital prognosis. ? Cardiac denervation can be safely performed in patients with refractory ventricular arrhythmia (VA). ? Stellate ganglion blockage is considered in patients with frequent VA refractory to medical treatment as well as catheter ablation and can be considered in long QT patients with refractory VA.
