Are you Canadian? Do you feel your heart pounding when you see Penguins legend Mario Lemieux? You may just be excited, or you may have a heart ailment like atrial fibrillation, which was one of the reasons Lemieux retired for good in 2006.
In this video (French here for you Quebec-ians), Lemieux discusses his bout with atrial fibrillation and warns others to educate themselves on the disease. Because that's what awesome people do...they help others.
So next time you're watching some Lemieux highlights and start to feel out of breath, call you doctor. Mario says so.
