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.

BACKGROUND:In patients with out-of-hospital cardiac arrest who present with an initial shockable rhythm, a longer delay to the first shock decreases the probability of survival, often attributed to cerebral damage. Delay to first shock was defined as the time from initial emergency call until the first shock by any defibrillator.
