You mention there are sometimes symptoms. How important are symptoms?


Symptoms that an individual perceives are obviously important – they may be the first clue to someone harbouring a potentially serious condition. There are several symptoms that a young individual needs to be aware of that would forewarn them that there may be a cardiac problem and these include chest pain, central chest pain described as a heaviness that is brought on by exertion and would leave by rest; breathlessness that’s disproportionate to the amount of exercise being performed; palpitation; dizziness or blackouts without warnings. About 20% of people who have died suddenly have exhibited these symptoms, 80% haven’t but up to one fifth of individuals will be identified merely on symptoms alone. So I think symptoms are very important and they should be taken very seriously.
