MedlinePlus: Cardiac Arrest Material about cardiac arrest (also called sudden cardiac death). "Sudden cardiac arrest occurs when the heart develops an arrhythmia that causes it to stop beating. This is different than a heart attack, where the heart usually continues to beat but blood flow to the heart is blocked." Includes links to material about treatment, research, statistics, and more.
