^u forgot pastor
Not enough time to think about a Pastor... I'm sure you can make peace with god without one if need be :-)
Now, you are mentioning the first 30min...
Statistically, speaking you will not be at the hospital at the first 30min.
Most probably, you will get a heart attack and call for help.
In 30min, the target is for you to arrive at the operation table.
Thus my list goes as follows:
Internist (it is the doctor you will call and has to diagnose your infraction! Mine was pretty bad :-/. In case it is your second+ heart attack you can skip this doctor and call an ambulance immediately saying you had and having again a heart attack this will save you time!)
Paramedic (The one that will take you to the hospital)
Emergency Room Specialist (I guess the one that prepares the operation room)
--- 30 min passed or you are already at the hospital ---
Anesthesiologist (I didn't needed one)
