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.

Effect of calcium ions on the heart rate?
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).
How muchchange in the heart rate of the frog did you see after the addition of calcium chloride?
The addition of calcium chloride typically increases the heart rate of a frog. This is because calcium ions play a crucial role in cardiac muscle contraction and excitability. The specific change in heart rate can vary depending on the concentration of calcium chloride used, but generally, an increase in heart rate is observed as calcium availability enhances the contractile force and frequency of heartbeats.

Does breathing effect you heart rate?
no
Does an increase in weight affect heart rate?
Yes. BMI does effect the heart rate. With more BMI, more will be the heart rate. With lesser BMI lesser will be the heart/pulse rate
