  2. Blood pressure - Wikipedia

    en.wikipedia.org/wiki/Blood_pressure

    Diastolic vs systolic blood pressure chart comparing European Society of Cardiology and European Society of Hypertension classification with reference ranges in children The risk of cardiovascular disease increases progressively above 115/75 mmHg, [ 13 ] below this level there is limited evidence.

  3. Blood pressure measurement - Wikipedia

    en.wikipedia.org/wiki/Blood_pressure_measurement

    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 ...

  4. Diastole - Wikipedia

    en.wikipedia.org/wiki/Diastole

    Early diastole is a suction mechanism between the atrial and ventricular chambers. [5] Then, in late ventricular diastole, the two atrial chambers contract (atrial systole), causing blood pressure in both atria to increase and forcing additional blood flow into the ventricles. This beginning of the atrial systole is known as the atrial kick ...

  5. Cardiac cycle - Wikipedia

    en.wikipedia.org/wiki/Cardiac_cycle

    See media help. The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. [ 1] It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, called systole. [ 1]

  6. Pulse pressure - Wikipedia

    en.wikipedia.org/wiki/Pulse_pressure

    Pulse pressure is the difference between systolic and diastolic blood pressure. [ 1] It is measured in millimeters of mercury (mmHg). It represents the force that the heart generates each time it contracts. Healthy pulse pressure is around 40 mmHg. [ 1][ 2] A pulse pressure that is consistently 60 mmHg or greater is likely to be associated with ...

  7. Diastolic function - Wikipedia

    en.wikipedia.org/wiki/Diastolic_function

    Diastolic function. In clinical cardiology the term "diastolic function" is most commonly referred as how the heart fills. [1] Parallel to "diastolic function", the term " systolic function" is usually referenced in terms of the left ventricular ejection fraction (LVEF), which is the ratio of stroke volume and end-diastolic volume. [2]

  8. Mean arterial pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_arterial_pressure

    D062186. In medicine, the mean arterial pressure ( MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [ 1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures ), and add that amount to the ...

  9. Hypertension - Wikipedia

    en.wikipedia.org/wiki/Hypertension

    This can mean that systolic pressure is abnormally high, but diastolic pressure may be normal or low, a condition termed isolated systolic hypertension. [69] The high pulse pressure in elderly people with hypertension or isolated systolic hypertension is explained by increased arterial stiffness , which typically accompanies aging and may be ...
