"What Causes Sudden Cardiac Arrest in Young People?"

The reasons for sudden cardiac arrest in young people include causes related to the heart itself, external to the heart, electrical shock injuries, and viral infections.

1. Causes Related to the Heart Itself: Conditions intrinsic to the heart can lead to sudden cardiac arrest in young people. For instance, sudden myocardial infarction, rupture of plaques in the anterior branch, and subsequent cessation of blood supply to the heart can cause sudden cardiac arrest. Sudden arrhythmia may also lead to sudden cardiac arrest.

2. External Causes to the Heart: External factors such as electrolyte disturbances and renal insufficiency can also result in sudden cardiac arrest in young individuals.

3. Electrical Shock Injuries: Electrical shocks involve the passage of current. If a large current passes through the heart, it can cause damage to the myocardium. Brief damage can affect the heart's conduction system and lead to sudden cardiac arrest.

4. Viral Infections: Viral infections can cause chronic arrhythmias, which can then lead to sudden cardiac arrest. Severe viral infections are more prone to causing sudden cardiac arrest, especially in young people with cerebrovascular and cardiovascular diseases and lung conditions.
