What causes sudden cardiac arrest?
A wide spectrum of cardiovascular abnormalities may cause sudden cardiac arrest in young athletes. A minor defect may become deadly if the heart is challenged and the electrical order of the heart is disrupted. Heart defects that may lead to cardiac arrest can be genetic or acquired due to a serious virus. Cardiomyopathy is the hidden heart defect that most commonly leads to sudden cardiac arrest in young athletes. Long QT Syndrome, a disruption of the heart’s electrical rhythm is another cause. Any deformed heart valve, artery, or vessel also can cause sudden cardiac arrest, as can heat stroke, medications and illegal drugs.
