Detailed explanation-1: -Diastolic pressure describes the lowest pressure within the large arteries during heart muscle relaxation between beating.
Detailed explanation-2: -Blood pressure is measured using two numbers: The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.
Detailed explanation-3: -The relaxation phase is called ventricular diastole, and during this period pressure in the aorta and pulmonary arteries falls to lower values called diastolic pressure.
Detailed explanation-4: -When your heart rests between beats, the pressure in the arteries is the diastolic blood pressure. This is why your blood pressure has two numbers: The top number is the systolic blood pressure. The bottom number is the diastolic blood pressure.
