What is the greatest risk factor for Sudden Cardiac Arrest in children?

Congenital heart defects pose the greatest risk factor for Sudden Cardiac Arrest (SCA) in children due to their direct impact on the heart's structure and function. These defects can lead to arrhythmias or impaired cardiac output, increasing the likelihood of life-threatening events.

Children with congenital heart defects often have abnormal heart anatomy or electrical conduction issues, which can predispose them to dangerous heart rhythms. This risk is particularly pronounced during physical exertion or stress, making it critical for caregivers and medical personnel to monitor these children closely.

While conditions such as asthma exacerbations, severe dehydration, and epileptic seizures can lead to serious complications and emergencies, they do not have the same direct and consistent link to cardiac abnormalities and sudden cardiac events as congenital heart defects do. Therefore, identifying congenital heart defects is vital for preventing SCA in the pediatric population.
