Didn't you ever watch Emergency? Oh, you're too young to remember that
show. They always squirt some gel on a paddle and rub the paddles
together to distribute the gel. That gel makes good electrical contact
with the skin.
Once you do that, your water/ion-filled cells in your body, including
your heart, can conduct.

Ok, perhaps I asked the question poorly. I don't want to know how the
device works, exactly, I want to know how the current is transported
through the body. That's the conductor? What makes the circuit?
Obviously, it has to be more than the skin. Or, is it an induction
