Blockade of the left ventricle of the heart
author: doctor Vasil'tsov AG
The heart muscle has special properties in comparison with other organs of the human body. One of these properties is the conductivity of impulses that arise in special structures of cardiac tissue. Sometimes it happens that the impulse is not transmitted by the cells of the heart. Such states are called blockades.
Blockade of the left ventricle of the heart or, as it is called in medical practice, the blockade of the left leg of the bundle of the Hyis is in most cases only a complication of the disease. Accordingly, if there is a lesion of the right leg of the bundle of His - there comes a blockade of the right ventricle of the heart . Diseases that can lead to blockade occur both in young (heart defects) and in old age (arterial hypertension, ischemic heart conditions, etc.).
Recently, blockade of the left ventricle is used as a term that has a more extensive concept than the "blockade of the left leg." This is due to the mechanism of momentum transfer. The fact is that the left leg of the bundle of His is divided into two legs: the front and the back. Sometimes the block occurs at the point of division into the anterior and posterior branches, in such cases the diagnosis of the level of the lesion is difficult. As a result, we decided to introduce a broader concept.
Kinds of blockades
In addition, left ventricular blockage may be complete and incomplete. Incomplete blockade does not pose any danger to life. Symptoms that are observed with her are weakness, slow heartbeat (bradycardia). If an incomplete blockade is detected on the ECG, the signs of which are the deviation of the electric axis of the heart to the left and hypertrophy of the left ventricle, the main thing is to exclude myocardial infarction, which is very often "masked" in the lines of the cardiogram with incomplete left ventricular blockade.
Symptoms and ECG
The main tool in diagnosing "blockade ..." is an electrocardiogram, which can look in the same cases in different ways, although it is made on the same apparatus.
The situation is very serious with a complete blockade of the left leg of the bundle of His (blockade of the left ventricle). First I would like to tell you what is happening in the norm: the left ventricle "responds" for the discharge of blood, saturated with oxygen, into the aorta. With the inability of the left ventricle, the oxygenated blood is delayed or stopped, which leads to an oxygen starvation of all organs and systems (primarily the brain). Clinically, this is manifested by breathing disorders, dizziness, drowsiness, a decrease in the rhythm frequency to 25 beats / min, and, at the end, an outlet to acute heart failure that can result in death if not provided with timely and correct medical care.
Diagnosis of complete blockade, from an experienced doctor, does not cause any special difficulties. Everything will be visible on the ECG. Provided if there is no other pathology.
Very often there is a complete blockade and myocardial infarction or a complete blockade and unstable angina. Much more difficult and with the treatment of complete blockade. To date, there are no specific recommendations on this matter. The main thing is to stop an acute condition, and then not to allow repetitions, so to say to carry out prophylaxis. Also read about the consequences of a complete blockade of the left leg of the bundle of His .
Such a state is differently differentiated, reaching the flesh, before using an electrodefibrilator. Then, when the condition is stabilized, drug therapy is administered, prescription drugs improving the quality of life (beta-blockers, etc.), antiarrhythmic drugs.
They advise to follow a diet (often blockades occur against obesity). All this for the elderly, who, so to speak, "acquired" diseases. For persons with defects, the most optimal treatment is a heart surgery to eliminate the defect. Another direction in the treatment is the installation of an electrocardiostimulator. In modern conditions, the approach to all patients is individual.

Arrhythmia is the wrong rhythm of the heart, which can be too fast - more than eighty beats per minute (tachycardia) or too slow - less than sixty beats per minute (bradycardia).

Incomplete blockade of the right leg of the bundle of His (abbreviated as NBPPG) is a partial violation of the patency of the electric pulse through the right leg of the bundle.

The attending physician appointed you an electrocardiogram: a squeaking apparatus, a whole heap of wires with suction cups and a long tape covered with mysterious curves, as a result. What do these teeth and knolls say?
In a nutshell, unfortunately, the technique of decoding the ECG will not tell. However, it is possible and necessary to understand the causes and significance of those changes that the specialist will identify. For example, if it is an inconvenient abbreviation - PBSCH, also known as a complete blockade of the right leg of the bundle.

The main indications for cardiac bypass grafting and those conditions in which aortocoronary shunting is recommended are singled out. The main testimony of only three and each cardiologist should either exclude these criteria or identify them and refer the patient to the operation:
- obstruction of the left coronary artery by more than 50%;
- narrowing of all coronary vessels by more than 70%;

Atrioventricular blockade of degree II or cardiac blockade of grade II is characterized by impaired, delayed or interrupted atrial pulse transmission through the atrioventricular node to the ventricles.

To treat the pain syndrome, neurologists often appoint a blockade, some kind of medication. This method of treatment refers to young enough compared to others, for example, massage, manual therapy, acupuncture, surgical methods.
Blockade aims to get rid of the very pain and its causes, using the minimum amount of time, resources and forces.

The maximum androgenic blockade is one of the ways to treat prostate cancer. This disease is a tumor that develops under the influence of male sex hormones - androgens (testosterone).

Each of us at least once in a lifetime felt pain in the neck. The reasons for such pain are many. The most common cause is degenerative changes in the cervical spine, the so-called cervical osteochondrosis. One of the effective methods of treating pain in the neck are therapeutic blockades. This is the administration of a drug substance to specific sites for therapeutic purposes.

Conduction through the sinoatrial connection in the heart can be disrupted for various reasons. It can be of several degrees, each of which has a different effect on the patient's well-being. The lightest degree of this blockade is the 1st degree. This is the initial and minimal damage to the conduction system in the heart, namely, its sinoatrial connection.

The heart is a unique organ that guides itself, that is, has automaticity, but, of course, taking into account the needs of the body and not without interference in the work of the nervous and endocrine systems. This organ is not just a muscle bag, which is a pump for pumping blood, the heart is much more complicated than it might seem.

It often happens that the terms of cardiologists and incomprehensible records in the description of ECG frighten and confuse patients, which leads to the appearance in the everyday life of non-existent diagnoses. The blockade of the right ventricle of the heart is the wrong name for a completely different concept. Therefore, it is not superfluous to clarify and understand the "blockades" and "ventricles."

The bundle of the Hyis is a system that provides the delivery of an electrical impulse to the cells of the heart, as a result of which these cells contract. The correct operation of all structures of the bundle of the Hyis provides an organized reduction of all cardiac cells, and the heart contracts as a solid organ.
