Automated External Defibrillator Arrhythmia Detection in a Model of Cardiac Arrest due to Commotio Cordis
Key result
A commercially available AED demonstrated 98% sensitivity and 100% specificity for recognizing ventricular fibrillation in a swine model of commotio cordis, successfully terminating all episodes.

Implication
AED accuracy in swine commotio cordis is encouraging; leaves open translation to pediatric athletes pending human data.
Study Design
Type
RCT (n=26)
Randomization
1, 2, 4, or 6 minutes of ventricular fibrillation
Structured PICO
Does an automated external defibrillator accurately detect and terminate ventricular fibrillation in a juvenile swine model of commotio cordis?
P
Population
26 anesthetized juvenile swine undergoing 50 ventricular fibrillation inductions via precordial impact from a baseball (model of commotio cordis relevant to young children)
I
Intervention
Automated external defibrillator (AED) applied after 1, 2, 4, or 6 minutes of ventricular fibrillation
C
Comparator
Different time intervals of ventricular fibrillation before defibrillation (1, 2, 4, or 6 minutes)
O
Outcome
Sensitivity and specificity of the AED for recognition of ventricular fibrillation, and successful termination of the arrhythmiasurrogate
In a juvenile swine model of commotio cordis, a commercially available AED accurately detected and successfully terminated ventricular fibrillation, supporting its potential life-saving use in children on athletic fields.
Cite This Study
Link et al. (2003) conducted an RCT in Cardiac arrest due to commotio cordis (n=26). Automated external defibrillator (AED) vs. Different time intervals (1, 2, 4, or 6 minutes) was evaluated on Sensitivity for recognition of ventricular fibrillation. A commercially available AED demonstrated 98% sensitivity and 100% specificity for recognizing ventricular fibrillation in a swine model of commotio cordis, successfully terminating all episodes.
