Coughing during a heart attack?

Question

I was reading an article on how coughing could help you stay conscience during a heart attack, later, I searched it up on google and I read an article saying that that was false! So now, Im confused. Does coughing only help in certain cases, certain times? Thanks!

Answer 1

I think you might of misinterpreted the article.  The are certain cardiac arrythmias that can revert with coughing, although I've been present when this has been attempted, I've never seen it work successfully.  

Answer 2

No, its false. Some people have heart attacks & don't know it. So, they're conscious the whole time. But if you're having the big one - coughing is not going to help
