Left-sided ultrasound-guided stellate ganglion block paradoxically caused a sudden, transient increase in arrhythmic events in a patient with presumed genotype-negative Long QT Syndrome.
Case Report (n=1)
No
This is the first documented case of a paradoxical increase in ventricular arrhythmia burden following left-sided stellate ganglion block, highlighting the need for cautious application in patients with comorbidities.
Ultrasound-guided left-sided or bilateral stellate ganglion block (SGB) has emerged as an effective bedside intervention for malignant ventricular arrhythmias (VA) refractory to conventional therapies, with demonstrated safety and efficacy in multiple studies. We report a medically complex patient with presumed genotype-negative Long QT Syndrome (LQTS) who experienced a sudden, transient increase in arrhythmic events shortly after an uncomplicated left-sided ultrasound-guided SGB. To our knowledge, this is the first documented case of increased VA burden following left-sided SGB, highlighting the potential for paradoxical effects and the need for cautious application in patients with comorbidities.
Bouvette et al. (Fri,) conducted a case report in Presumed genotype-negative Long QT Syndrome (LQTS) with malignant ventricular arrhythmias (n=1). Left-sided ultrasound-guided stellate ganglion block (SGB) was evaluated on Arrhythmic events. Left-sided ultrasound-guided stellate ganglion block paradoxically caused a sudden, transient increase in arrhythmic events in a patient with presumed genotype-negative Long QT Syndrome.
