Introduction to capillary pulsation sign

There are many mysteries in the human body that are not easy to discover in daily life. What I will explain to you next is the capillary pulsation sign. What is the cause of this disease? I believe that all of you are very unfamiliar with it. Let us learn about it next.

Peripheral vascular signs refer to a group of physical signs that result from increased pulse pressure leading to increased peripheral arterial and capillary pulsations, such as water pulse, obvious carotid pulsation, nodding movement, capillary pulsations, gunshot sounds, and double murmurs.

1. Reasons

It is common in diseases such as aortic valve insufficiency, patent ductus arteriosus, ruptured aortic sinus aneurysm, arteriovenous fistula, hyperthyroidism, severe anemia, and aortic sclerosis in the elderly.

2. Generation mechanism

The above diseases all lead to increased aortic systolic pressure, decreased diastolic pressure, increased pulse pressure, rapid rise and then rapid drop in the pressure in the peripheral blood vessels, and increased pulsation amplitude, thus producing a series of peripheral vascular signs.

3. Inspection method

(1) Water-rush pulse: The pulse rises and falls suddenly, like the surging tide, hence the name water-rush pulse or sinking pulse. It was first described by Corrigan, so it is also called Corrigan pulse. Examination method: Raise the patient's forearm above the head, and the examiner holds the palm of the wrist tightly with his hand, and the water pulse can be clearly felt.

(2) Obvious carotid artery pulsation

The pulsation of the carotid artery in a normal person is only visible when the cardiac output increases after strenuous activity, and it is very weak and difficult to see when the person is at rest. If there is obvious pulsation of the carotid artery in a resting state, it is abnormal, which is common in the above-mentioned diseases with increased pulse pressure.

We have a general understanding of one of the main causes of capillary pulsation sign. In daily life, we must pay attention to our physical health, especially in normal times, we should exercise and keep fit to protect our body's immunity. To prevent the occurrence of disease.
