Arrhythmias & electrophysiology
Factors Associated with Stellate Ganglion Block Success in Recurrent Ventricular Arrhythmias
Authors' conclusion
In this multicentre experience, SGB was similarly effective despite the aetiology of cardiomyopathy, type of arrhythmia, laterality, and inotropic or mechanical support. SGB was less effective for the suppression of ventricular arrythmias at 24 h for the elderly.
