Left Stellate Ganglion Blockade for Refractory Ventricular Arrhythmias With Aconitine Poisoning: A Case Report.

ABSTRACT

Aconitine poisoning causes refractory ventricular arrhythmias (VAs). In a 20-year-old man, VAs of unknown etiology did not respond to drugs and electrical defibrillation. However, left stellate ganglion blockade (SGB) dramatically decreased arrhythmias without complications. At a later date, we found that refractory VAs were caused by aconitine poisoning. Left SGB is effective for treating refractory VAs with aconitine poisoning and can be easily performed with few complications for VAs of unknown etiology even if patients are receiving anticoagulant therapy. Also, left SGB can be performed to diagnose refractory VAs.
