Cardiac arrest from high potassium treatment in er?

High potassium. Yes I have seen this and had a family with several who died from it. Well in them they were treating low K and got it too high. So need more information. Happy to do 2nd opinion.

What mechanism that high potassium causes cardiac arrest? I just know high k+ causes hyper excitability of cells?

Cell repolarization. When cardiac muscle cells fire, they use up part of the electrochemical gradient they maintain in life. They are repolarized by an outward potassium (K+) flux across the plasma membrane. This outward K+ current depends on the K+ electrochemical gradient. If the "outside" K+ (in blood & interstitial fluid) is very high, that destroys the K+ electrochemical gradient, the cells can't repol; they stop. Read more...
