cough/heart attack

[ForumGal]

Friends,
Coughing to save yourself from a heart attack is an (old) urban legend.
See the website: http://urbanlegends.about.com/library/blcpr.htm The
wording at the site is exactly the same as the wording in the message below.
Would be nice if it were true. Best, Margaret

Without help, the person whose heart stops beating
properly and who begins to feel faint, has only about
10 seconds left before losing consciousness.

However, these victims can help themselves by coughing
repeatedly and very vigorously. A deep breath should
be taken before each cough, and the cough must be deep
and prolonged, as when producing sputum from deep
inside the chest.
