Why the study?
Percutaneous stellate ganglion blockade is frequently used for electrical storm, but its efficacy in reducing ventricular arrhythmia events and mortality remains undefined.

SGB may reduce VA events in electrical storm; supports randomized trials before changing practice.
Does percutaneous stellate ganglion blockade reduce ventricular arrhythmia events and mortality in adult patients with electrical storm?
Percutaneous stellate ganglion block significantly reduces ventricular arrhythmia burden in patients with electrical storm, though short-term mortality remains high, highlighting the need for definitive randomized controlled trials.
