Died suddenly and unexpectedly?
Been treated for recurrent fainting?
Had unexplained seizures, drowning or car accidents?

B) Lifestyle Factors
Q. Have you ever been told you have:
High blood pressure?
Q. Are you a heavy smoker?
Q. Have you ever felt dizzy, fainted or passed out when exercising?
Q. Do you ever have chest tightness, coughs or wheezing during or after a run?
Q. Have you ever been treated/ hospitalized for asthma?
Q. Have you ever had a seizure?
