Has your child fainted or passed out during exercise, emotion or startle?
Has your child fainted or passed out after exercise?
Has your child had extreme fatigue associated with exercise (different from other children)?
Has your child ever had unusual or extreme shortness of breath during exercise?
Has your child ever had discomfort, pain or pressure in his chest during exercise?
Has your child ever been diagnosed with an unexplained seizure disorder?
Family History Questions
Are there any family members who had an unexpected, unexplained death before age 50? (include SIDS, car accident, drowning, others)
Are there any family members who died of heart problems before age 50?
Are there any family members who have had unexplained fainting or seizures?
If you answer yes to any of the questions, your doctor should check your child's heart.
