What is the difference between a Heart Attack and Sudden Cardiac Arrest
What is SCA
SCA is the condition in which the heart unexpectedly ceases to function. It happens suddenly and without warning. Often this is because of irregular and rapid quivering of the heart's lower pumping chambers (ventricles) called ventricular fibrillation. When this occurs, blood stops flowing to the the brain and other vital organs, causing loss of consciousness or seizure-like activity in seconds. If not treated within minutes, SCA results in death.
What is a Heart Attack
A heart attack is when blood flow to the heart is blocked. A heart attack occurs when a blocked artery is not reopened quickly, the part of the heart normally nourished by that artery begins to die. The longer a person goes without treatment, the greater the damages.
Resuscitation from SCA
The normal rhythm of the heart can only be restored with defibrillation through an electrical shock that is safely delivered to the chest by an automated external defibrillator (AED).
