A defibrillator is a medical device that can deliver electrical shocks to restore normal heart rhythm. This condition can occur in people with various types of heart disease, including problems with the heart arteries or inherited heart rhythm disorders. The study will compare two different treatment approaches for stopping these dangerous heart rhythms.

One treatment being tested is a procedure called percutaneous stellate ganglion block, which involves injecting numbing medications near specific nerves in the neck area that can affect heart rhythm. For this procedure, doctors will use bupivacaine hydrochloride and lidocaine hydrochloride monohydrate, which are medications that temporarily block nerve signals. The other treatment is amiodarone hydrochloride, which is a medication given through a vein that is commonly used to control abnormal heart rhythms and is considered the standard treatment for this condition.

The purpose of this study is to find out if the nerve block procedure works better than amiodarone at completely stopping dangerous heart rhythm episodes in the first three hours after treatment. Participants will be randomly assigned to receive either the nerve block procedure with the numbing medications or the amiodarone medication. Doctors will then monitor how many dangerous heart rhythm episodes occur during the three hours following treatment to determine which approach is more effective at preventing these episodes.
