I'm looking for someone well-versed in anatomy—specifically the heart and the electrical impulses in the body—to help me with some research. I can use my google-fu all I like, but sometimes google doesn't yield the exact answers I need (and, um, I never took anatomy so I need someone to dumb down some of the technical stuff for me).

I have a few very specific questions so I shouldn't take up too much of your time (unless you'd like to become my medical expert in which case, I'm sure I will have MANY more questions).

Thanks!

(Recommendations of who to ask or where to ask are also welcome. Is there a medical community like military_beta?)
