A patient in a hospital bed isn't of any real concern with this. There will be no alarms or nurses running if the device is disabled, only if the patient's heart stops. And their heart would have stopped either way, because the ICD isn't keeping their heart running. It's there in case it stops, and if they're in a hospital bed there will be people around ready to attend to them if their heart stops.
