Sudden Cardiac Arrest (SCA) is the leading cause of death in the U.S., taking the lives of more than 300,000 people each year. On average, this is more than the total amount for breast cancer, lung cancer, stroke, and HIV/AIDS combined.
During SCA, heart function ceases abruptly and without warning. In contrast, a heart attack, which is caused by “plumbing” problems, such) as a blocked artery, is customarily preceded by warning signs such as chest pain and other symptoms.
When SCA strikes, the heart is no longer able to pump blood to the rest of the body, and the victim loses consciousness, resulting in death more than 90% of cases. SCA is an “electrical” problem, whereby an arrhythmia prevents the heart from pumping blood to the brain and vital organs.
