What does the term 'diastolic' specifically refer to in blood pressure measurements?

The term 'diastolic' specifically refers to the pressure in the arteries during the heart's recovery phase, which occurs when the heart is between beats. This is when the heart muscle is relaxed, allowing the chambers to fill with blood. During this phase, the pressure in the arteries is at its lowest point, which is crucial for determining overall cardiovascular health. Accurate measurement of diastolic pressure is essential as it helps assess the heart's efficiency and the resistance of blood vessels during the relaxation phase. A precise understanding of diastolic pressure provides insights into issues related to hypertension and overall cardiovascular risk.
