According to the Mayo Clinic, pacemakers and implantable cardioverter defibrillators (ICDs) are safe from
WiFi-enabled PDAs. The study apparently only tested the effects WiFi-enabled PDAs had when placed near a
pacemaker, not the effects of WiFi signals in general (and especially not the effects of overpowered long-range hacked
WiFi tools, but we digress). But we suspect that if it's safe to stick a WiFi receiever next to your chest, you
don't have to worry about making a trip to granny's with your WiFi gadgets in tow.
