Many states have passed laws requiring AEDs in health clubs, fitness centers and gyms since these are places where individuals have an increased risk of cardiac arrest from overexertion, a blow to the chest, and many other reasons. If you are exercising at a health club and your heart goes into a potentially fatal rhythm, your survival may depend on a shock from an AED. The American Heart Association encourages AEDs at all types of fitness centers, but specifically recommends them for centers that cater to people at higher risk of cardiac events (senior citizens, people with disabilities, centers for cardiac rehabilitation, etc.) States that require an AED at fitness facilities include Arkansas, California, Iowa, Illinois, Indiana, Louisiana, Massachusetts, Maryland, Michigan, Mississippi, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, District of Columbia.
