Sudden Cardiac Arrest

Sometimes sudden cardiac arrest happens in seemingly healthy athletes. In these cases, it often means the athlete has an undiagnosed condition, such as an enlarged heart or cardiomyopathy.

Cardiac arrest can happen in seemingly healthy athletes.

Causes

According to the American Academy of Pediatrics (AAP), there are many causes of cardiomyopathy in children, including some that are not fully understood. Common causes include:

  • Inheriting the condition from one or both parents
  • A viral infection
  • Toxins affecting other organs
  • Using chemotherapy drugs
  • Metabolic, mitochondrial or systemic diseases in parts of the body other than the heart

  • Chest pain or discomfort during physical activity
  • Fainting or near fainting without warning or during physical activity
  • Seizure without warning or during physical activity
  • Excessive fatigue associated with exercise
