An erratum to this article was published (JAMA Netw Open, 4 Nov 2024 ↗)
Authors' conclusion
In this cohort study of patients with OHCA and VF or pVT, AP defibrillator pad placement was associated with higher ROSC compared with AL placement.
Study context
- Population
- Adults with out-of-hospital cardiac arrest (OHCA) and initial emergency medical services (EMS)-assessed ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT) receiving EMS defibrillation, single suburban fire-based North American EMS agency, July 2019–June 2023
- Participants
- 255 adults
- Exposure
- Anterior-posterior (AP) vs anterior-lateral (AL)
- APn = 158
- ALn = 97reference
- Outcome
- Return of spontaneous circulation (ROSC) at any time
Methodological detailssingle EMS agency, consecutive patients
- Single EMS agency
- Consecutive patients
