Pulse pressure is the difference between two indicators obtained when measuring blood pressure using the Korotkov method, that is, between systolic (upper) and diastolic (lower) pressure. Pulse pressure reflects the state of the cardiovascular system and is an important diagnostic criterion for many pathologies.

PD is easy to calculate, knowing systolic and diastolic pressure; Blood (arterial) pressure (BP) is usually written in the form of two digits separated by a fraction. The maximum indicator is written first (denominator of the fraction), this is systolic pressure. It shows with what force the blood presses on the walls of the vessels at the time of the contraction of the heart (systole). The minimum indicator is called diastolic, it characterizes the total resistance of blood vessels. The difference between these two indicators, expressed in millimeters of mercury. st. (written as mmHg. st. ), called pulse pressure (PD).

It is often mistakenly believed that it is necessary to calculate the heart rate to determine the AP, but in fact, the AP and heart rate are completely different indicators..

What PDV can tell about at the time of contraction, the heart pushes a certain volume of blood (stroke volume) into the vascular system, which causes stretching of the blood vessels. During diastole, vessels, due to the elasticity of their walls, return to their original volume. Under the influence of certain diseases, as well as age-related changes, the vessels in a person lose their natural elasticity and elasticity. As a result, they become stiff and unable to adequately respond to the pulse wave, which leads to an increase in the AP.

By the value of PD, the doctor judges the state of the vascular walls, vascular obstruction, the presence of vascular spasm.
