Pulse Pressure Measurement

Pulse Blood Pressure (PP) is an index of the cardiovascular system. Pulse blood pressure is calculated as the difference between systolic and diastolic pressure.
It has been proved that the pulse pressure level is an important factor affecting the development of complications in patients with various cardiovascular diseases.
The pulse pressure level can adequately reflect the “real age” of arterial vessels, which does not always coincide with their “biological age”.
As a rule, pulse pressure in healthy adults at rest is about 30-60 mm Hg.

Low (reduced) pulse pressure

Low pulse pressure – the difference between systolic and diastolic blood pressure is less than 30 mmHg, for example, 125/100 mmHg.
The most common causes:

  • reduction in the stroke volume of the heart left ventricle (tamponade, constrictive pericarditis or aortic stenosis);
  • excessive tachycardia, when the filling time of heart ventricles dramatically decreases;
  • shock due to increase in peripheral vascular resistance;


High (elevated) pulse pressure

High pulse pressure the difference between systolic and diastolic pressure is over 60 mmHg, for example, 140/70 mmHg. High pulse pressure is very harmful to the body, because it accelerates the natural aging of internal organs, especially heart, brain and kidneys.
The most common causes:

  • increased stiffness of large arteries;
  • hyperkinetic syndrome;
  • atherosclerosis;
  • chronic heart failure;
  • anemia;
  • pregnancy;
  • anxiety;
  • heart block;
  • endocarditis;
  • increased intracranial pressure.

In the case of significant change (decrease or increase) in pulse pressure, it is mandatory to consult a doctor.
