Which component corresponds to arterial pressure during heart relaxation?

During the heart’s relaxation phase, the arteries are not being actively pressurized by a new wave of blood; instead, the pressure in the arterial system reflects the pressure left in the arteries as they recoil and as the ventricles are filling. This resting arterial pressure is called diastolic pressure, the minimum pressure in the arteries during a cardiac cycle. Systolic pressure is the high pressure during ventricular contraction, pulse pressure is the difference between systolic and diastolic pressures, and mean arterial pressure is a time-averaged value over the cycle. So the component corresponding to arterial pressure during heart relaxation is diastolic pressure.
