A child/young adult should seen by a doctor if she/he has experienced below:

• Family history of unexpected, unexplained sudden death (under the age of 40).
• Do you get unusually short of breath during or shortly after exercise?(not explained by just being unfit!)
• Do you get palpitations (eg, heart racing fast, missing beats, fluttering sensation, irregular pulse rate, thumping sensation in chest)?
• Fainting as a result of emotional excitement/distress/startle?
