Nerve block injection may tame deadly heart storms
NCT ID NCT07211347
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a procedure called a stellate ganglion block, where a numbing medicine is injected near nerves in the neck to calm severe, repeated episodes of dangerous heart rhythms (electrical storm). The trial will involve 64 adults with heart disease who have not responded to standard treatments. Half will receive the injection, and the other half will not, to see if it reduces life-threatening heart events by at least 50% within 12 hours.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
stellate ganglion block (lidocaine and bupivacaine injection)
What this could lead to
If it works, this could provide a new, less invasive way to control life-threatening heart rhythm emergencies when standard treatments fail.
What could go wrong
This is a small, early-phase trial with only 64 participants, so results may not apply to everyone. The procedure carries risks like bleeding or nerve damage, and it may not reduce arrhythmias as hoped.
