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.
