This stopped his pacemaker, and the next day he was admitted to hospital in Portugal. He remained there for 5 days
The surprising thing here is that the effect was not more immediate ( ie cardiac arrest after going through the AMD ) if the pacemaker was rendered U/S.
As in the case of people like diabetics who have to carry needles on long flights, in this sort of case a doctor's note clearly explaining about the pacemaker might have made the security staff more receptive.
It certainly warrants a complaint to the airport's management.
