Working Together to Save More Lives Sudden Cardiac Arrest, or SCA, is among the leading killers of Americans, claiming an estimated 350,000 people each year. More people die of sudden cardiac arrest than breast, lung, colon, and prostate cancer combined. More than 90 percent of people who experience SCA will die, representing a national survival rate that has not significantly changed in more than 30 years.
AEDs save lives. An automated external defibrillator (AED) is a lightweight, portable device. It delivers an electric shock through the chest to the heart when it detects an abnormal rhythm and changes the rhythm back to normal.
