Sudden Cardiac Arrest is a Leading Cause of Death
Sudden cardiac arrest (SCA) claims the life of 475,0001 people in the United States each year.
SCA occurs when the heart stops beating normally due to an electrical malfunction in the heart, typically caused by ventricular arrhythmias. It can lead to a loss of consciousness and potentially death if not treated within minutes.
Approximately 70% of SCAs occur at a home or residence and about 50% of those are unwitnessed.
Rapid defibrillation is the only proven therapy to reverse sudden cardiac arrest.
