Big pulse volume? Do you mean stroke volume? If so, that is because CO (cardiac output) = HR (heart rate) x SV (stroke volume).

Basically if you have a low heart rate (bradycardia) in order to compensate for cardiac output, your stroke volume will increase.

Slow heart rate means increased diastolic filling time . Fill the ventricle more means more stroke volume.
