What treatment did you receive in hospital, and how many hours later was that? What could QF crew have done on-board? They are equipped with defibrilator and oxygen, but doesn't sound like either of these would have helped you in any way ... is that correct? Or were you diagnosed as having had a stroke or heart attack?

It amazes me how many people board a flight when they are feeling unfit to travel; something I've observed in the past decade of numerous flights. Maybe we need the temperature checks at the boarding gate
