What is Sudden Cardiac Arrest?
Sudden cardiac arrest (SCA) is the sudden loss of heart function as a result of a malfunction of the heart’s electrical system. SCA is more common in athletes when compared to their non-athlete counterparts because of the increased risk associated with strenuous exercise.
Is Sudden Cardiac Arrest the same as a heart attack?
No. A heart attack is the result of a lack of blood flow to the heart itself because of a blockage to a vessel, not an electrical malfunction. The lack of blood flow to the heart muscle causes the heart to stop beating.
What happens during Sudden Cardiac Arrest?
> The heart stops beating effectively.
> Bloodflow to the brain and other vital organs decreases.
> Oxygen is not delivered to the brain and other vital organs causing the person to faint.
> Normal heart rhythm must be restored within 4 minutes to avoid brain damage and within 10 minutes to avoid death.
What are the most common causes of SCA?
Heart Structure Abnormality is a defect with the structure of the heart.
Electrical Cardiac Abnormality is a malfunction of the electrical system of the heart.
Acquired Cardiac Abnormality is a malfunction of the heart that develops after birth.
Commotio Cordis is a sudden blow or impact to the chest causing an electrical malfunction.
