During the contraction of the heart into the vascular system is pushed another portion of blood. Kick her in the artery wall creates vibrations which spread through the vessels to the periphery gradually fade. They received the name of pulse.
In the human body there are three varieties of blood vessels: arteries, veins and capillaries. The ejection of blood from heart one way or another affects each of them, forcing their walls to oscillate. Of course, as the arteries closest to the heart vessels more susceptible to the cardiac output. The vibrations of their walls well-defined palpation, and in the large vessels visible to the naked eye. That is why arterial pulse is the most significant for diagnostics.
Capillaries-the smallest blood vessels in the human body, but even they reflected the work of the heart. Their walls vary in the rhythm of heart contractions, however normal it can be determined only by special devices. Visible capillary pulse – sign of pathology.
Vein removed from the heart so that their walls do not fluctuate. The so-called venous pulse – the transfer of vibrations from nearby large arteries.
What is the value for the diagnosis are the fluctuations of the vascular walls? Why is it so important?
The Pulse gives an indication of the hemodynamics, about how effectively reduces the cardiac muscle, the fullness of the vascular bed, the rhythm of heart beats.
In many pathological processes modified pulse characteristic of the pulse ceases to conform to the norm. This allows to suspect that the cardiovascular system is not all right.
In violation of generation of the pulse by the heart muscle the rhythm of heart contractions is changing and with it changes the pulse. Separate oscillations of the vascular walls begin to fall, or to appear prematurely, or to follow each other through unequal intervals.

Arrhythmia if you change the work of the sinus node (the area of the myocardium that generates impulses that lead to contraction of the heart muscle):
Ectopic arrhythmias. Their appearance is made possible by the emergence in the myocardium of the hearth with the activity higher than the sinus node. In this situation, the new pacemaker will suppress the activity of the latter and impose the rhythm of your heart contractions.
Violation of the pulse to the myocardium (the blockade). Depending on the localization of the problem, hindering the normal progress of the nervous impulse from the sinus node blockade are divided into groups:
Separately should stay on and flicker predserdy and ventricles. These States are also called absolute arrhythmia. The sinus node in this case ceases to be a pacemaker and the myocardium of the Atria or ventricles are formed multiple ectopic foci of excitation that sets the heart rhythm with great frequency reduction. Naturally, in such circumstances, the heart muscle is not able to adequately contract. Therefore, this pathology (especially of the ventricles) is life-threatening.
Heart rate at rest for adults is 60-80 beats per minute. Of course, this is for life change. Pulse rate by age is significantly different.
Table pulse | |
Age | Heart rate (beats per minute) |
1st month | 130 - 140 |
1 month – 1 year | 120 – 130 |
1 – 2 years | 90 – 100 |
3 – 7 years | 85 – 95 |
8 – 14 | 70 – 80 |
20 – 30 years | 60 – 80 |
40 – 50 years | 75 – 85 |
Over 50 years | 85 – 95. |
Perhaps the discrepancy between the number of heartbeats and the number of pulse waves. This occurs when the bloodstream is thrown a small blood volume (heart failure, reducing the amount of circulating blood). In this case, vibrations of the vessel wall may not occur.
Thus, the pulse of the people (normal age is indicated above) is not always determined on peripheral arteries. However, this does not mean that the heart is also not reduced. Perhaps the reason is the reduced ejection fraction.
Depending on the changes in productivity to changes in the pulse. Characteristics of the pulse at the voltage it provides for the division into the following types:
Depending on the changes in productivity of the following types of pulse:
This figure combines the filling and voltage pulse. It depends primarily on the expansion of the arteries during contraction of the heart and falling it in the relaxation of the myocardium. Largest of the following types of pulse:
