Sudden cardiac arrest is the leading cause of death among young athletes in the U.S., where about 2,000 people under the age of 25 die each year, according to the American Academy of Pediatrics. Among high school students, one death occurs every three days. In contrast, the Centers for Disease Control reports only 1.5 deaths per year from sports-related concussions. A typical cause is undiagnosed congenital heart disease, such as coronary artery abnormalities or disorders of the heart's electrical system, such as ventricular fibrillation. Without immediate medical intervention, the victim will die within minutes. A quick defibrillator can restore the heart to a normal rhythm. A study from the New England Journal of Medicine showed that communities with comprehensive AED programs, including CPR and AED training, achieved survival rates of up to 40 percent.[1]
