Diastole (/ d aɪ ˈ æ s t ə l i / dy-AST-ə-lee) is the relaxed phase of the cardiac cycle when the chambers of the heart are refilling with blood. The contrasting phase is systole when the heart chambers are contracting. Atrial diastole is the relaxing of the atria, and ventricular diastole the relaxing of the ventricles.
In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] Usually, the blood pressure is read from the left arm unless there is some damage to the arm. The difference between the systolic and diastolic pressure is called the pulse pressure.
Mean blood pressure rises from early adulthood, plateauing in mid-life, while pulse pressure rises quite markedly after the age of 40. Consequently, in many older people, systolic blood pressure often exceeds the normal adult range, [33] if the diastolic pressure is in the normal range this is termed isolated systolic hypertension.
High blood pressure (stage 1): 130-139 systolic or 80-89 diastolic High blood pressure (stage 2): 140-179 systolic or > 90 diastolic Hypertensive crisis: > 180 systolic, and/or > 120 diastolic
Normal. Less than 120 and. Less than 80. Elevated. 120-129 and. Less than 80. Stage 1 Hypertension. 130-139 or. 80-89. Stage 2 Hypertension. 140 or higher or. 90 or higher
What’s the difference between systolic and diastolic blood pressure? You’ve likely heard your health care provider say your blood pressure is something like “120 over 80,” typically a ...
Diastole (at right) normally refers to atria and ventricles at relaxation and expansion together—while refilling with blood returning to the heart. Systole (left) typically refers to ventricular systole , during which the ventricles are pumping (or ejecting) blood out of the heart through the aorta and the pulmonary veins.
A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
