Sudden cardiac death refers to death that occurs unexpectedly and presumably due to a heart condition.
In sudden cardiac death the heart may:
a) Have an electrically chaotic rhythm, called ventricular fibrillation
b) Have no electrical beat at all, called asystole
c) Be so weak that it is unable to mechanically pump any blood
There are many causes for sudden cardiac death, which include severe heart failure, heart attack and certain inherited heart conditions.
It is imperative for bystanders to perform cardiopulmonary resuscitation (CPR) to improve the chances for survival for the victim.
