John C.R........You are spot on with your assumptions.

When I learned of the death of the poor guy, I let it upset me, and emotionaly broke down with the disapointment of not saving his life.
They were very kind and sympathetic toward me,the people in the A & R, room sat me down and explained that yourself and the passing Nurse had done everything you possibly could have, to help, unfortunately the damage he sustained to his Heart was fatal!.
From his medical record they learned he was taking extremely high dosage Beta blockers for high B.P. So I guess you could say he was a heart attack waiting to happen.
Unfortunately when it did occur it was a serious one.
