EKG Interpretation and the Physiology behind it.

There is one major subject that I would really like to see. That is EKG interpretation and the Physiology behind it. I believe this would be a subject that would benefit many EMS students as well as nursing students. EKG interpretation can be a challenging subject, but if Khan Academy made videos about it and the physiology behind it, I think it would help out a lot of students. If Khan Academy did start making videos about EKG interpretation, I would love to become a volunteer to review it as it is a subject I find very fascinating.
