Heart disease is the leading cause of death in the United States, according to the American Heart Association. Sudden Cardiac Arrest (SCA) occurs when the heart stops beating and without immediate assistance, the person will ultimately die where they fell. SCA is far different than a person experiencing a heart attack. A person suffering a heart attack may have chest pain, trouble breathing, and become nauseated and sweaty. If these symptoms are recognized quickly and the person is treated in a hospital, statistics show that 90% of heart attack victims will survive.
