From some local insiders i've heard, i can tell it was a trained and competent diver, who make an usual dive to the corvette V17 wreck (it's dived at least once a week), who make all the correct deco, and get joint pain and other moderate symptons. Within less than two hours was inside the chamber, and just as about to start the final ascent has a heart attack.
I've also heard that the diver has some previously diagnosed coronary disease and was aware of the risks (can't confirm on 100% sure). But i know some of the instructors who trayned him and are very competent people
