Narrative:

At cruise altitude the aircraft had a low pressure alert in the left engine driven electric generator. Procedure required a disconnect of the drive as well as starting of the APU. Considering an ETOPS crossing and a new burn rate with the APU I decided to divert to ZZZZ instead of continuing overseas. Coordination with dispatch confirmed that a fuel dump would be operationally preferred over an overweight landing. The dump was started at FL340 and this was a dump of approximately 67;000 pounds of fuel. Dumping stopped at 16;000 feet. On downwind I was informed that a passenger was experiencing seizures and was on the floor. I declared a medical emergency and was expedited to landing. As fuel dumping had stopped several minutes before we landed 5;000 pounds under structural landing weight. The sick passenger was met and deplaned by paramedics.
