Would you recognize the warning signs of pediatric sudden cardiac arrest (SCA)? If not treated in minutes, SCA can result in death.
In a new policy statement to be published online on Monday, March 26, the American Academy of Pediatrics (AAP) provides guidance for pediatricians on underlying cardiac conditions that may predispose children to SCA.
Although the risk for SCA increases when children with underlying cardiac disorders participate in athletics, SCA can occur at very young ages and also when a child is at rest.
Research supports the need for a SCA registry, says the AAP. A registry would help experts gain a better understanding of the nuances of the condition.
Plus, many cardiac disorders are known to be genetic, so the evaluation of family members, even if asymptomatic, could be a critical step in the overall diagnosis of disorders predisposing to pediatric and young adult SCA.
We asked Arizona Pediatric Cardiology Consultants (APCC), members of the Arizona Chapter of the American Academy of Pediatrics, to weigh in on what parents need to know about SCA.
How common is SCA?
According to the Centers for Disease Control, each year 2,000 individuals less than 25 years of age will die suddenly with the majority of these having a cardiac etiology.
What causes SCA?
Pediatric sudden cardiac arrest and sudden cardiac death can occur with various types of cardiac causes, including conditions in the heart muscle (such as hypertrophic cardiomyopathy), unusual positioning of a coronary artery, or an electrical disturbance within the heart. (Long QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia).
How are family members evaluated, and what symptoms may be indicators that a child is pre-disposed to this?
Signs that may suggest an increased risk for SCD include fainting or seizure with exercise, excitement, or startle, significant dizziness with exertion, unusual and consistent shortness of breath or chest pain with exercise.
If a family member has died suddenly or unexpectedly at a young age, has unexplained seizure disorder, died at a young age from a heart problem, or has a history of fainting, then screening is appropriate.
How do doctors determine if a child is at risk? What tests are performed?
Evaluation by a pediatric cardiologist will include a thorough individual and family history, ECG, physical exam and perhaps an echocardiogram, an exercise stress test, and genetic testing if necessary.
Would automatic external defibrillators (AED) on playing fields and in schools help?
A great majority of these deaths relate to a life-threatening arrhythmia, ventricular fibrillation. CPR and use of an AED may be life saving. AEDs are often found in airports, casinos, and government buildings.
However, there is no law in Arizona currently requiring AED within schools, recreational sports fields, or other private facilities.
Are efforts being made to increase the availability of AEDs?
The decision about whether to have an AED on location is left up to the individual organization. APCC’s electrophysiologists are making an effort to educate schools, sports organizations, and families regarding the importance preparation to prevent SCD.
The role of an ECG in all sports physicals remains a debated topic within the United States. It is, however, very important to ask specific questions (use the attached screening tool) for risk factors and then refer to a pediatric cardiologist for further assessment.
What should parents or caregivers do if they believe a child might be at risk?
Once an individual is identified as having any of the conditions listed above, it is very important for first degree relatives to also be evaluated by a pediatric cardiologist even if they are not experiencing symptoms.
Sudden Cardiac Death is devastating to not only the families of those affected but to the communities in which they live. Educating families, schools, sports leagues, and primary care providers about quick and effective screening for children at risk for SCD is a first step in prevention.
Increased community awareness and the availability of AEDs in schools and sporting venues will help avert a tragedy.

Check with your child’s physician if you are concerned about risks for SCA.
