What is a common cause of sudden cardiac arrest in children?

Sudden cardiac arrest in children can have various causes, and one of the most common is congenital heart defects. These are structural problems with the heart that are present at birth and can lead to arrhythmias or other heart-related issues that significantly increase the risk of cardiac arrest. These defects may go undetected for some time, and they can manifest as serious conditions later in life or even in childhood, leading to sudden and unexpected cardiac events.

While trauma, respiratory issues, and heart attacks can also lead to cardiac arrest, they are not as prevalent in this specific age group as congenital heart defects. Trauma is often associated with accidents and injuries, which can lead to cardiac issues but is less frequent. Respiratory issues can certainly lead to cardiac arrest, particularly in very young children, but they typically do not directly cause it as often as congenital heart issues. Heart attacks are rare in children compared to adults, as they are often linked to lifestyle factors and pre-existing heart disease that are more common in older populations.
