Detailed explanation-1: -Left stellate ganglion block may shorten the QT interval, whereas right stellate ganglion block lengthens the QT interval.
Detailed explanation-2: -There are some expected changes that result from blocking the sympathetic nerves. These changes are temporary and may last about 4-6 hours.
Detailed explanation-3: -What are the risks of a stellate ganglion block? Side effects of the procedure may include: Bruising or soreness at the injection site. Drooping eyelids.
Detailed explanation-4: -A stellate ganglion can directly regulate the activity of the cardiac sympathetic nerve and then regulate cardiac activity. Enhanced discharge activity of stellate ganglion can accelerate heart rate and raise blood pressure (48).
