If you believe in literature and folk art, the heart is a very sensitive organ that knows how to love, feel, think, in addition, it is very fragile. From the point of view of medicine, only the last statement is correct, in spite of the fact that it is the most powerful muscle in the body, working without sleep and rest throughout life. The main task of the heart is to ensure the movement of blood through the vessels, and it begins to perform it in the process of intrauterine development. With pathologies of the cardiac system, the body is put under attack, since the importance of the correct functioning of this organ is very high, it is difficult to exaggerate. One of such pathologies is the blockade of the legs of the bundle of His. When blockade (complete or incomplete), the normal patency of the sinus pulse in the cardiac system is violated, more precisely its path and time of passage. This impulse, when formed in the sinus node, should excite the atrial system. If this does not happen, it does not happen in a routine manner. Violations are different: dangerous (complete blockade) and not very (incomplete). One of the serious dangers of blockade is the distortion of the results of the electrocardiogram, which makes it difficult to diagnose many heart diseases, in particular myocardial infarction.
The blockade of the left leg of the bundle of Guis - what is the essence?
Blockade of the left leg of the bundle of the Hisnus (or BLNGG) is a pathology based on the defeat of the cardiac apparatus at various levels. For example, the left leg in the trunk of the bundle of His can be affected. Or the main trunk of the left leg before branching. Both the anterior and posterior branches of the leg can be simultaneously affected after the site of their excretion from the body of the main trunk. Also, the left half of the septum between the ventricles is damaged, and both legs are involved in the process. The reason may also be expressed in diffuse changes of the myocardium in the peripheral branches of the posterior and anterior branches. With BLNPG it is difficult to pass excitation to the myocardium of the left ventricle on the left leg. It is carried out in an unusual way, as a result of which the QRS complex broadens, and the direction of repolarization in the left ventricle changes. We will not consider this in detail, this is a task for cardiac specialists. Let's consider some features of this disease. Leg injury can be the result of fibrotic processes that are associated with coronarosclerosis and less often with limited myocarditis (syphilitic, rheumatic, diphtheria, infectious). It is very rare, but it happens that the blockade occurs with an absolutely healthy heart. There is a complete and incomplete blockade of the left leg of the bundle of His. If it is a complete, excitement first covers only the septum between the ventricles, and not the entire ventricle completely. Incomplete blockade develops in cases of abnormalities in the exchange of electrolytes, or overdose with drugs, or various kinds of intoxication. Because of this, the typical conductivity of the cardiac system is disrupted, and there is no full excitation of the left side. Diagnosis of this violation can be done with the help of an ordinary electrocardiogram, when decoding will be visible changes.
Is it dangerous?
If the blockade has spread only to one leg, then no, it is not dangerous for life, although there is certainly nothing good in this. Many modern cardiologists believe that this deviation has already ceased to be a deviation in those cases when it is not a consequence of other heart diseases. Danger of complete blockage of both legs, in such cases it is required to implant a pacemaker.
Blockade of the left bundle branch leg: treatment and prevention
The main curative measure, topical with incomplete blockade, is the identification of the disease that caused the blockade and its treatment. Specific therapeutic complex is not a violation. In cases where the patient suffers from hypertension, dangerous heart failure or angina, special therapy is required, associated with the support of the cardiac apparatus. It is carried out on the basis of preparations with the content of cardiac glycosides, hypotensive and antiarrhythmic agents. With congenital heart disease, the blockade requires exceptionally prompt intervention. It happens that for young people this blockade is the norm, this can only be established by a specialist after a series of studies. Remember that self-medication can be dangerous to your health, especially when the question touches the heart. Be healthy!
