Diastolic pressure is associated with which heart phase?

Diastolic pressure is defined as the pressure in the arteries when the heart is in a state of relaxation, specifically during the diastole phase of the cardiac cycle. During diastole, the ventricles of the heart fill with blood from the atria, and the heart muscle is at rest. This relaxation phase allows the chambers of the heart to expand and fill with blood, which is crucial for maintaining adequate circulation. The measurement of diastolic pressure reflects this phase, as it indicates the lowest pressure in the arteries as the heart prepares for the next contraction.

Understanding diastolic pressure in relation to the phases of the cardiac cycle demonstrates the importance of heart relaxation for effective blood circulation and overall cardiovascular health.
