19. Which ions resulted in arrhythmia of the frog heart?

Calcium ions, sodium ions, and potassium ions all caused arrhythmia of the frog heart.

20. Which ion had the greatest effect on the frog heart? Explain.

Potassium ions had the greatest effect because increased potassium (hyperkalemia) decreases the resting potential of cardiac muscle plasma membranes, thus decreasing the force of heart contraction.
