The pressure in the arteries during heart relaxation is known as?

The pressure in the arteries during heart relaxation is referred to as diastolic pressure. This term specifically describes the phase of the cardiac cycle when the heart is at rest between beats and the chambers are filling with blood. During this phase, the pressure in the arteries is at its lowest, reflecting the resistance to blood flow when the heart is not actively pumping. Understanding diastolic pressure is important for assessing cardiovascular health, as it helps in evaluating conditions like hypertension where this pressure can be elevated.

On the other hand, systolic pressure refers to the pressure during the contraction of the heart when blood is pumped out into the arteries, while cardiac pressure is not a commonly used term in this context. Pulsatile pressure refers to the fluctuation of blood pressure during the cardiac cycle but does not specifically denote the pressure during heart relaxation.
