Resting cardiac muscle cells are most permeable to4 Predict Question 1: Because calcium-channel blockers are negative chronotropic andnegative inotropic, what effect do you think increasing the concentration of calcium will haveon heart rate?1 Predict Question 2: Excess potassium outside of the cardiac cell decreases the restingpotential of the plasma membrane, thus decreasing the force of contraction. What effect (ifany) do you think it will initiallyhave on heart rate?2
