Comparing defibrillation techniques for out-of-hospital cardiac arrest
Official title: Strategies for Defibrillation During Out-of-Hospital Cardiac Arrest - A Randomized Clinical Trial
Run by Aarhus University Hospital · NCT06781892 · Data updated 2026-11-12
This study tests different ways to use defibrillators on adults who have a cardiac arrest outside of the hospital to see which method works best to restart their hearts.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who have experienced an out-of-hospital cardiac arrest with a shockable rhythm.
✕Probably not a fit
Patients with cardiac arrest due to trauma or those for whom posterior pad placement is not feasible may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The STRAT-DEFI trial investigates different defibrillation strategies for adults experiencing out-of-hospital cardiac arrest. It compares standard anterior-lateral pad positioning with anterior-posterior positioning and double-sequential defibrillation. Participants are randomly assigned to one of three groups to evaluate the effectiveness of these techniques in restoring normal heart rhythm. The trial aims to determine which method yields the best outcomes for patients in critical situations.
Why it matters
Potential benefit: If successful, this study could improve survival rates and outcomes for patients experiencing out-of-hospital cardiac arrest.
How similar studies have gone: While there have been studies on defibrillation techniques, this specific comparison of double-sequential defibrillation is relatively novel and has not been extensively tested.
