Cardiac arrest

Sudden or unexpected loss of heartbeat

Cardiac arrest, also known as sudden cardiac arrest (SCA), is a condition in which the heart suddenly and unexpectedly stops beating or beats in a way which fails to produce pulse. When the heart stops, blood cannot circulate properly through the body and the blood flow to the brain and other organs is decreased. When the brain does not receive enough blood, this can cause a person to lose consciousness and brain cells begin to die within minutes due to a lack of oxygen.
