325,000 Americans die each year of sudden cardiac arrest. Some of these deaths could be prevented through the timely use of an automated external defibrillator (AED). The inability to locate AEDs in such emergency situations greatly reduces their intended life-saving impact. Citizen scientists can help by reporting locations of AEDs throughout Philadelphia.

The University of Pennsylvania has developed a crowdsourcing mobile media contest called the MyHeartMap Challenge to find AEDs and raise awareness. Participants will use a free app to identify and record locations in Philadelphia county. The primary goal is to create a complete and up-to-date map of AEDs in Philadelphia.
