=== Effect of delayed treatment ===
Uncorrected, these cardiac conditions (ventricular tachycardia, ventricular fibrillation, asystole) rapidly lead to irreversible [[brain damage]] and death, once cardiac arrest takes place. After approximately three to five minutes in cardiac arrest,<ref>{{cite web|publisher=American Red Cross|url=http://www.americanheart.org/presenter.jhtml?identifier=4483|access-date=2008-10-27|title=Cardiopulmonary Resuscitation (CPR) Statistics

For every minute that a person in cardiac arrest goes without being successfully treated (by defibrillation), the chance of survival decreases by 7 percent per minute in the first three minutes, and decreases by 10 percent per minute as time advances beyond ~three minutes.<ref>American Red Cross.
