>The older designs that used magnetic coupling to communicated required holding a bulky device right next to where the pacemaker was implanted may have been annoying to use, but that kind of roadblock is a feature for pacemakers and other devices where changing the battery requires major surgery. Right, not so unexpectedly, physically limiting access to devices (air gapped) remains the safer practice.
