APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Diastole is the relaxation of the chambers of the heart and systole is the contraction of the heart chambers. Systolic pressure is thus the pressure that your heart emits when blood is forced out of the heart and diastolic pressure is the pressure exerted when the heart is relaxed.

Detailed explanation-2: -For the right ventricle, systolic pressure is normally 25 to 30 mm Hg, with end-diastolic pressures of 5 to 7 mm Hg. The systolic pressure in the left ventricle increases with age and should equal the systolic arterial pressure. The end-diastolic pressure is typically less than 10 mm Hg.

Detailed explanation-3: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection. Systole and diastole occur in both the right and left heart, though with very different pressures (see hemodynamics below).
