Hell, yes.  Just think of the phenomena you have in the body:
mildly-conductive fluids moving through tubes in a mildly-conductive
matrix.  Now introduce an enormous magnetic field.  Every moving
ion will experience a BxV force, and every blood vessel which is
not parallel to the ambient field becomes an MHD generator of
DC current (pulsating in the arteries, closer to continuous in
the veins).

I'm not sure if the currents would be enough to short out the
neural circuitry which controls the heart, but I wouldn't want
to find out personally.  It sounds dangerous.

Yes, I'm a real double-E.
