9. Sudden Cardiac Arrest

Sudden cardiac arrest (SCA) is an acute event in which the heart’s electrical system fails and stops beating. It is most often caused by ventricular fibrillation, which is when the ventricles of the heart begin to beat irregularly. SCA is unpredictable and can occur in people with no pre-existing heart conditions. It is most often fatal, though the use of an automated external defibrillator (AED) can save the patient's life.
