Could someone please explain why an increase in potassium would cause a decrease in HR? I need someone to really dumb it down for me so I can fully understand. i was thinking that more Ka+ would increase the HR but in my lesson, it said it would slow down HR. I don't understand. Thank you very much!
Isn't Potassium involved in muscle relaxation after contraction? Not enough and you get cramps... Too much and you relax to death?????
