Answer 1

Minor quibble you instantly collapse on cardiac arrest (heart stop beating) not necessarily on heart attack (oxygen supply to part of heart cut off, usually a blocked coronary artery). Someone with a heart attack can be walking and taking, cardiac arrest very much not. And of course a heart attack can lead to cardiac arrest.

Have heart disease myself so very aware of this distinction!
