Detailed explanation-1: -A stellate ganglion block (sympathetic block) is an injection of local anesthetic into the front of the neck.
Detailed explanation-2: -These results suggest that the left stellate ganglion contributes more sympathetic tone to the myocardium than the right. This explains why most human studies use unilateral left SGB for treatment of ventricular arrhythmias [7••, 13••].
Detailed explanation-3: -The stellate ganglion is a collection of sympathetic nerves found anterior to the neck of the first rib. It may occasionally extend to being anterior to the transverse process of the C7 cervical vertebra.
Detailed explanation-4: -The left and right stellate ganglia provide the majority of the sympathetic innervation to the heart via post-ganglionic fibers, although the left stellate ganglion is quantitatively dominant at the ventricular level.
