Sudden cardiac arrest is the ultimate 911 emergency. It is an ‘electrical’ problem, in which the heart suddenly stops beating. Death can occur in a matter of minutes — unless a bystander decided to step in and starts cardiopulmonary resuscitation (CPR). If you witness a person suddenly collapsed and not breathing, they are likely suffering from a sudden cardiac arrest and requires immediate CPR and defibrillation to survive.
