Pressure in chambers of the heart

[royzizzle]

I'm looking for a info source containing systolic,diastolic/mean pressure in all four chambers of the heart.

also, what does a mean pressure in a heart chamber even mean? Do the left and right atria not have systolic and diastolic pressure?

I don't understand that diagram. how come there is only left atrial and ventricular pressure portrayed? what about the right atrium and right ventricle? also, where is diastole and systole on the diagram?
