Thishyperkalemia(excess potassium) decreases the resting potential of the cardiac musclecell. What effect do you think this would have on the force of contraction? Page 4 of 4 Describe the effect that increasing the calcium ions had on the heart in this activity. Howwell did the results compare with your prediction?1 Describe the effect that increasing the potassium ions initially had on the heart in thisactivity. Relate this to the resting membrane potential of the cardiac muscle cell.
