Reduced Risk of Sudden Death From Chest Wall Blows (Commotio Cordis) With Safety Baseballs
Key result
Safety baseballs propelled at 40 mph significantly reduced the risk of ventricular fibrillation in a swine model compared with standard baseballs (11-22% vs 69% of impacts).
Why the study?
Do safety baseballs reduce the risk of ventricular fibrillation from chest wall impacts compared to standard baseballs in a juvenile swine model of commotio cordis?

Implication
Hypothesis-generating for safety baseballs in youth sports; prospective human trials needed before any practice change.
Structured PICO
Do safety baseballs reduce the risk of ventricular fibrillation from chest wall impacts compared to standard baseballs in a juvenile swine model of commotio cordis?

Safety baseballs significantly reduce the risk of ventricular fibrillation from chest wall impacts in a swine model of commotio cordis compared to standard baseballs.
Cite This Study
Link et al. (2002) studied Commotio cordis (n=40). Safety baseballs vs. Standard baseballs was evaluated on Ventricular fibrillation (VF). Safety baseballs propelled at 40 mph significantly reduced the risk of ventricular fibrillation in a swine model compared with standard baseballs (11-22% vs 69% of impacts).
