Calcium has no effect on heart rate. It does, however, have an effect on how hard the heart squeezes (inotropic effect). Heart rate is effected by the slow sodium channels in the pacemaker cells in the right atrium (and other pacemaker cells if the SA node is malfunctioning).

What was the effect of sodium ions on heart rate?
increases the heart rate
What effect does changing the concentration of calcium ions have on the coagulation of milk?
the rate of coagulation increases as the concentration of calcium ions increase.
What effect does calcium have on the heart rate?
The resting membrane potential is maintained by the distribution of positive and negative charged ions across both sides of the cell membrane. At rest, calcium concentration in cells of the heart is low as compared to the outside. At action, calcium channels in the membranes open, thereby allowing calcium to rush into the cells. So raising the heart rate.
Does the heart rate stabilize and remain stable with calcium ions?
No, until 23C Ringer solution is applied
What effect changing the concentration of calcium ions has on the rate of coagulation of milk?
Rennin is an enzyme that converts the soluble milk protein caseinogen into the insoluble protein paracasein, producing the curd that can be processed into cheese or other milk products. Inorganic ions such as metal ions can act as cofactors. The ion may combine with either the enzyme or the substrate to reduce the activation energy. These ions are called activators. Activators are thought to make the enzyme substrate complex form more easily. For example, the action of amylase on starch is quicker in the presence of chloride ions. Calcium ions are required to activate the enzyme rennin. In this demonstration, calcium ion is removed by precipitating it as calcium citrate. In the tube containing the sodium citrate, calcium citrate forms as a precipitate. what effect changing the concentration of calcium ions has on the rate of coagulation of milk how calcium ions influece the activity of rennin in bringing about the coagulation of milk because it does
What is a calcium block?
Calcium blockers (or calcium channel blockers) are chemicals used in drugs to disrupt the movement of calcium ions through calcium channels present in various cells. Their effect is used to reduce hypertension (excessive blood pressure), mitigate large vessel stiffness, alter heart rate, prevent vessel constriction, alleviate angina (chest pain) and also may have applications as migraine preventers and painkillers.

What effect does Pilocarpine have on the heart rate?
Pilocarpine lowers the heart rate.
Can emotions effect heart rate?
Yes, they can, usually by increasing heart rate.
