Because athletes young and old can suffer cardiac arrest, some states have mandated the placement of automated external defibrillators (AEDs) in gyms, stadiums and other sports venues. But a new study finds the use of AEDs by bystanders for cardiac arrest at athletic sites didn't improve much after states enacted these laws.

Bystander use of automated external defibrillators (AEDs) can improve survival from sudden cardiac arrest (SCA), but utilization remains extremely low, attributable in part to poor access. We hypothesized that AED placement and utilization can be facilitated by identifying SCA event high-density areas in the community.
