No, for a variety of reasons... For starters, there _are_ ways to disable it externally, but they use a fairly specialized magnet. Secondly, even if they could shut it off, the patient isn't really in a position to know if it's shocking them for a legitimate reason or not. Shutting it off may simply shut their heart off... Finally, the security properties of Bluetooth aren't exactly up to the standards I would like to see for a "can deliver a fatal shock to someone's heart" type device.
