Cardiac Physiology and Action Potential Movies

In Physiology class today, we talked about cardiac physiology and the action potentials for heart contraction.  it was a lot of information to soak up, so I went looking for some additional sources.  I found a handful of movies by Walid Aziz (aka hyperhighs) on youtube that are simple, but he has a knack for explaining things.  I’ve collected the links here that are relevant to my class, but he has posted many more videos on physiology and anatomy.
