Dicrotism

Dicrotism is a phenomenon associated with a doubling of the pulse wave, which can be heard with each heartbeat. This phenomenon is observed in typhoid fever and can be designated by the term “dicrotic”.

To better understand dicrotism, it is necessary to consider the process of blood circulation in the body. The human heart is a pump that pumps blood through the vessels, providing tissues and organs with the necessary nutrients and oxygen. With each contraction of the heart, blood is pushed into the aorta, which is the main arterial vessel, from where it is distributed throughout the body.

A pulse wave is a wave that is transmitted along the walls of the arteries as blood is pushed out of the heart. With a normal pulse, the wave passes through the arteries once per heartbeat cycle. However, with dicrotia, there is an additional reflection of the wave from the aortic wall back to the heart. This causes the pulse wave to double its beat and create a second sound that can be heard when listening to the heart.

Dicrotism can be caused by various factors, but the most common cause is typhoid fever, a severe infectious disease caused by the bacterium Salmonella typhi. With this disease, bacteria affect the intestines and lymph nodes, which leads to damage to the walls of blood vessels. This, in turn, can cause dicrotism.

Other factors that can cause dicrotia are:

1. high blood pressure;
2. disturbances in the functioning of the aortic valve;
3. heart failure;
4. hyperdynamic states of the body.

Diagnosis of dicrotia can be made by listening to the heart with a stethoscope. Additional tests, such as electrocardiography (ECG), can be used to identify the causes of dicrotism.

In general, dicrotia is an unusual phenomenon that can be caused by various factors. Although it is usually associated with typhoid fever, it is important to remember that this is not the only cause of its occurrence. If you suspect dicrotia, see your doctor for diagnosis and treatment.

Dicrotism is a doubling of the pulse wave, heard with each heartbeat. Dicrotia is observed in typhoid fever.

Dicrotia is a pathological sign in which an additional wave is recorded on the sphygmogram - a dicrotic notch. This is because the aortic valves do not close completely, causing some of the blood to flow back into the left ventricle.

The cause of dicrotia in typhoid fever is weakening and depletion of the myocardium due to intoxication. Dicrotic pulse is one of the classic symptoms of this disease.

Dicrotic pulse can also be observed in other conditions accompanied by cardiac damage, for example, infective endocarditis, myocarditis, pericarditis.

Introduction

Dicrotia is a medical term that refers to the procedure for determining the pattern of a patient's pulse. This can be a very useful way to assess a person's health, as it shows what activity the heart is producing and what abnormalities may exist.

Indications for determining dicrotia

The definition of dicrotism can be useful in diagnosing certain conditions, such as:

− Hypertension: dicrotic waves can occur during periods of high blood pressure. In addition, the appearance of dicrotic waves is often accompanied by interruptions in the functioning of the heart and a deterioration in its contractile function.

- Heart failure: a dicrotic wave can appear in diseases associated with insufficient oxygen supply to the heart muscle. This indicator indicates that the blood is poorly supplied with oxygen, which reduces its ability to expand and fill the heart, and also impairs the functioning of the myocardium.

In people suffering from these diseases, one can also observe inhibition of reverse contraction, expansion of systolic pressure and shortening of the phase of the cardiac cycle. An examination using “autosegmental” technology for dicrotic wave monitoring makes it possible to detect cardiac arrhythmias in the early stages. In addition, the definition of dicrotism is important in determining the individual characteristics of a healthy person. Taking certain medications can negatively affect heart rhythm due to the specific substances they contain.

Dicrotia is one of the signs of typhoid fever and is characterized by a doubling of pulsation in the heart muscle after each heart contraction. This symptom occurs when blood pressure decreases, which may be accompanied by tachycardia or bradycardia. However, the main symptom is not dicrotia, but specific blood changes caused by the bacteria Salmonella typhi.

Typhoid fever is caused by the bacteria S. typhi, which is often contracted through food and water or through contact with infected people. Symptoms of typhoid fever vary depending on the severity of the infection, but the main ones are fever, nausea, vomiting and diarrhea. If complications occur, this can lead to dehydration, exhaustion, and even coma.

The most common diagnostic method for typhoid fever is to detect bacteria in the blood. A specific antigen of S. Typhimurium is used to diagnose the disease, although another common cause of the symptom of dicrotism is a change in rheological
