   Cardiac arrest
   means the heart has suddenly stopped beating. There is no pulse or breathing. The commonest cause is a chaotic electrical pattern caused by a ventricle or heart muscles being damaged or starved of oxygen. Causes include heart attack, severe blood loss, suffocation, electric shock, anaphylactic shock, drug overdose, and hypothermia.

   Cardiac arrest
   A `cardiac arrest`, also known as `cardiorespiratory arrest`, `cardiopulmonary arrest` or `circulatory arrest`, is the abrupt cessation of normal circulation of the blood due to failure of the heart to contract effectively during systole. A cardiac arrest is different from (but may be caused by) a `heart attack` or myocardial infarction, where blood flow to the still-beating heart is interrupted. `Arrested` blood circulation prevents delivery o...
