Re: high immunity
That would depend on how much attenuation the human body provides, and the coupling efficiency to the pacemaker wiring. Both of which would depend on the frequency of the threat. I have done no HPM work, but I expect we are talking about microwave (1 GHz +) threats. I think the attenuation would increase and clearly coupling efficiency would decrease with increasing frequency. 5,000 V/m coupled to a 10 GHz tuned dipole would generate about 25 Volts. I expect that the duration of the transient would be well below 1 microsecond. I don't know any physiology, but I expect that a 1 ns to 1 us transient is much less harmful than 1 ms transient. By the way, a 10 GWatt ERP source generates 5000 V/m at about 30 meters.
