I think that it is impossibly difficult to comment on this incident if you weren't actually there at the time. Trying to debate 'what they should have done' is ridiculous.
None of the crew are doctors, nurses or medical practiioners, nor do we know if any doctors were on-board and treated the patient. Clearly, the crew acted in the patient's best interests based upon the symptoms presented and the information available to them at the time. The fact that initially a heart attack was reported indicates that the crew believed that they were presented with a life threatening situation, hence the diversion. I doubt that a decision to divert is ever taken lightly.

To try to belittle, degrade or criticise the actions of the crew at this point is totally uncalled for and completely arrogant.

Actual passengers that have commented say that the crew were fantastic at all times and I applaud them for that. They did a great job.
