    I went to Howstuffworks.com and did a search. They don't have a direct explanation about how EKG machines work, but they did have a link to this interesting site:


    That site is more about interpreting the EKG trace, not about how the machine measures it.

    Then I googled ekg machine electrode circuit and got lots of good hits. Here's the first one:


    "A Portable, Low-Power, Wireless Two-Lead EKG System"

    Hope that helps. -Mike-
