I was recently reading about a propsal to give police access to 'EMP Guns' for use in stalling the engines of vehicles, but one of the concerns about the idea was if the driver had a pacemaker... From what I understand, regular EMP shielding (in the form of sheet metal,) would be entirely unsuitable. And, I think, the electrodes connected to the patient's heart would fire. Would it be possible to shield against an EMP by using a high powered electromagnetic field? (EG - do magnetic fields expend energy on each other when they intersect?) Also, if this were a high altitude detonation of a nuclear bomb, would the radiation responsible for causing the EMP negate this somehow?
