Commotio Cordis & Cardiac Safety

We’re proud to serve as a national leader in research support to help eliminate the risk of serious injuries like commotio cordis.

The best way to reduce the risk of commotio cordis in lacrosse is with the use of chest protection equipment that meets NOCSAE performance standard ND200.

what is Commotio cordis?

Commotio cordis is a Latin term, meaning “agitation of the heart.” It’s a rare, but serious, medical condition that is caused by low-impact trauma to the chest, including by a projectile such as a lacrosse ball or baseball. This impact can cause the heart to change its normal rhythm and lead to sudden cardiac arrest. Immediate CPR and defibrillation is necessary to restore the heart rhythm.

developing better protection

Beginning in 2021, USA Lacrosse boys’ and girls’ youth rules mandated that all goalie chest protectors must meet the new NOCSAE standard. It’s also mandatory in the NFHS boys’ and girls’ high school rules, and the NCAA men’s and women’s rules. Beginning in 2022, USA Lacrosse boys’ field players, NFHS boys’ field players, and NCAA men’s field players must also wear chest protection that meets the NOCSAE ND200 standard. Products are now available.

AED Grants

The most effective treatment for sudden cardiac arrest and the only effective response to commotio cordis is the timely delivery of a life-saving shock or defibrillation. Automated External Defibrillators (AED) are portable and easy-to-use devices that deliver potentially life-saving defibrillation therapy quickly and effectively. USA Lacrosse strongly encourages an on-site AED for all games and practices. The combination of immediate CPR and defibrillation with an AED can more than double a cardiac arrest victim’s chance of survival.

Grant recipients receive an AED from stryker, the official AED provider of USAL.
