An erratum to this article was published (Eur Heart J, 14 Oct 2024 ↗)
Authors' conclusion
The findings of this large, prospective, multicentre study provide evidence in favour of the effectiveness and safety of PSGB for the treatment of refractory ES.
Study context
- Population
- Patients with electrical storm refractory to standard treatment, 19 centres, 1 July 2017 to 30 June 2023
- Participants
- 131 patients184 percutaneous stellate ganglion block (PSGBs)
- Exposure
- 12 h after vs 12 h before percutaneous stellate ganglion block
- PSGBn = 131
- Outcome
- Reduction of treated arrhythmic events by ≥50%, 12 h after vs 12 h before PSGB
- Follow-up
- 12 h
Methodological detailssingle-arm
- Single-arm
