Re: How wireless are we talking?
My Pacemaker (Medtronic 4194) was implanted in 2009, and, for the curious, sits just below my shoulder blade. During my annual checkup, the reader, a small PC mouse-shaped device is perched over the scar. It's positioning is quite delicate, and 1/2" out of place will see the comms drop off.
So, tor the moment, this is restricted to an attack via the hospital equipment, or a prolonged personal attack (Asleep, passed out in a bar etc)
Whilst the devices will improve their range, this will require a bigger battery. As there is no wireless charging option available yet, this requires a re-fit every 7-10 years.
Hold on, this sounds familiar...... Fixed battery, dedicated software analysis by a "technician", expensive to install, difficult to service, proprietary software, limited connectivity - damn it - I have seem to have an iPacemaker.
