Pacemaker hack can deliver deadly 830-volt jolt

Pacemakers from several manufacturers can be commanded to deliver a deadly, 830-volt shock from someone on a laptop up to 50 feet away, the result of poor software programming by medical device companies.

Maybe someone needs to educate this reporter to the significance between amps(joules) and volts. For perspective, an external defibrillator delivers about 1000 volts of electricity but only about 300mA. An implanted Defibrillator delivers about 750 volts.

The concept of delivering a volt is not well understood by most people. A volt is a way of defining a difference in electrical potential. Basically, voltage in a circuit is like water pressure differences in a pipe. One volt means that one joule of energy can be delivered per Coulomb of charge that passes through two points with a potential of one volt.
