The MyHeartMap Challenge was a contest that ran from January 31 to March 27, 2012. Participants submitted photographs of the locations of more than 1,200 automated external defibrillators (AEDs) throughout Philadelphia. The data collected is being used to create an interactive map of AED locations to help bystanders better access these life-saving devices during sudden cardiac arrest events, which will be distributed to emergency response services as well as the public. We are still accepting submissions to help improve the database – sign up and submit an AED location today!
