Cardiac arrest, (also known as cardiopulmonary arrest or circulatory arrest)

•  is the cessation of normal circulation of the blood due to failure of the heart to contract effectively.^[1] Medical personnel can refer to an unexpected cardiac arrest as a sudden cardiac arrest or SCA.
• A cardiac arrest is different from (but may be caused by) a heart attack, where blood flow to the muscle of the heart is impaired.
• Arrested blood circulation prevents delivery of oxygen to the body.
•  Lack of oxygen to the brain causes loss of consciousness, which then results in abnormal or absent breathing.
•  Brain injury is likely if cardiac arrest goes untreated for more than five minutes.^[3][4][5] For the best chance of survival and neurological recovery, immediate and decisive treatment is imperative.^[6]

Cardiac arrest is a medical emergency that, in certain situations, is potentially reversible if treated early.
When unexpected cardiac arrest leads to death this is called sudden cardiac death (SCD).^[1] The treatment for cardiac arrest is
cardiopulmonary resuscitation (CPR) to provide circulatory support, followed by defibrillation if a shockable rhythm is present. If a shockable rhythm is not present after CPR and other interventions, clinical death is inevitable.
