Efficacy of early use of percutaneous stellate ganglion block for electrical storms
Authors' conclusion
Percutaneous stellate ganglion block is proved to be effective also when used early in the treatment of ES.
Study context
- Population
- Patients with electrical storm in the STAR registry, 1 July 2017 to 30 April 2024180 percutaneous stellate ganglion block (PSGB)
- Participants
- 180 patients
- Exposure
- Early PSGB vs delayed PSGB
- Early PSGBn = 26
- Delayed PSGBn = 154reference
- Outcome
- Effectiveness of the first PSGB: treated arrhythmic events in the hour after vs the hour before PSGB

Main finding
As reported in the abstract
Treated arrhythmic events, hour after vs hour before PSGB
| Group | Value | Events hour after vs hour before |
|---|---|---|
| Early PSGB | −4.5 (range −7–-2) | 0 (0-0) vs. 4.5 (1-10), P < 0.001 |
| Delayed PSGB | −2.5 (range −3.5–-1.5) |
Value
Early PSGB−4.5 (range −7–-2)
Delayed PSGB−2.5 (range −3.5–-1.5)
Events hour after vs hour before
Early PSGB0 (0-0) vs. 4.5 (1-10), P < 0.001
Delayed PSGB— not stated in the abstract
- Early PSGB vs Delayed PSGB: P = ns — extent of reduction similar
Observational data: associations, not effects.
