What s the deal with intramural conduction delay ?

Intraventricular conduction retardation "heart block:

According to the severity, it can be divided into degree (conduction delay), degree (partial stimulation and missed pulse), degree block (complete interruption of conduction);

According to the location of occurrence, it is divided into: sinus block, intraatrial block, atrioventricular block, and intraventricular block;

According to the course of change, it can be divided into permanent, temporary, alternating, and progressive block.

The axis deviates to the right", and the normal deviation should be slightly to the left. Because the heart is on the left. Axis deflection is generally influenced by the anatomical position of the heart, the mass ratio of the ventricles on both sides, age, and body size.

Right axis bias to right ventricular hypertrophy, left posterior branch block, etc. Right ventricular hypertrophy is predominantly seen in cor pulmonale. If the deviation is not large, there is no need to rush, and it is not clinically significant.

It is recommended to go to the hospital for a detailed examination, the results of the physical examination are not seen, and the conclusion can not be blindly made, and a simple examination is not easy to diagnose! It is recommended not to engage in strenuous exercise at first!

Intraventricular conduction delay, the professional term should be "intraventricular bundle branch block", there are left and right bundle branches in the ventricle, and the left bundle branch is divided into left anterior branch and left posterior branch, the specific treatment should be decided according to the degree and scope of the block and clinical symptoms, if you usually do not feel uncomfortable, heart rate, heart rhythm, blood pressure are normal, simple left or right bundle branch block does not need special treatment, if there are clinical symptoms (such as dizziness, palpitations, amaurosis), or accompanied by atrioventricular block (i.e., "three-branch block"), Pacemakers** should be considered. The right axis bias is due to the right ventricular hypertrophy, left posterior branch block, etc., and the diagnosis of ECG alone is not of great significance, so it is recommended to do cardiac ultrasound to take a look. In both cases, if there are no obvious symptoms, a moderate amount of exercise can be done.

For reference only).

Analysis: Normally, a specially differentiated cardiac conduction system ensures that each sinus impulse is synchronously transmitted from the atria to the ventricles, and if the impulses are abnormally delayed or blocked during the atrioventricular conduction, it is called atrioventricular block. Depending on the degree of block, it can be divided into first-degree, second-degree (partial), and third-degree (complete) atrioventricular block.

Pathogenesis: AV block can be caused by many causes, including acute rheumatic fever, viral and toxic myocarditis, cardiomyopathy, congenital heart disease, cardiac surgery, digitalis poisoning, - blocker or calcium-channel blocker overdose, hyperkalemia, etc., and AV block can also be congenital. In addition, AV block can also be present in patients with increased vagal tone, such as trained athletes.

Opinion: Clinical symptoms: Depends on the underlying heart disease, the degree of block, and the site of block.

First-degree AV block is often asymptomatic. Auscultation of the first heart sound is low and dull. Second-degree atrioventricular block is also often asymptomatic.

When the blocked heart beats are excessive, it can occasionally cause palpitations, chest tightness, fatigue, dizziness, etc. Auscultation may reveal arrhythmias and leaked beats. The clinical manifestations of third-degree atrioventricular block are mixed.

The child is asymptomatic, especially congenital, the child has a decrease in stroke volume, fatigue, dizziness, shortness of breath during activity, and in severe cases, it is manifested as Ass syndrome, and even sudden death.

I was a medical student in cardiology.

Come back from learning, let's put it this way, the heart is divided into left ventricle, right ventricle, left atrium and right atrium, imagine a field character, the upper two grids are the ventricles, the lower two grids are the atrium, the upper left grid corresponds to our right ventricle, and the right ventricle has a sinus node.

It excites the ventricles to contract and pump blood, which recontracts to pump blood into the atria, which contracts to pump blood into the blood vessels. The atria can only contract after the ventricles contract, so it depends on the conduction of the atrioventricular bundle to balance their time difference so that the ventricles contract and the atria just start to contract, once the atrioventricular conduction time is prolonged, which is what we call atrioventricular block.

, it can lead to the atrium and ventricle diastolic rhythm is disrupted and cause a series of diseases, if you want to continue to talk about it, you can't finish typing at night, and you will have to go to the hospital tomorrow, the basics are roughly these, I hope you can understand. 25 years old is so young, it's about the same age as me, take good care of your body!

Hello, it may be that the atrium is blocked and the conduction time is prolonged, if it is long, the consequences are serious, conduction block is when the sinus node emits an impulse: in the process of transmission from the atria to the ventricles, due to physiological or pathological reasons, there is a partial or complete, temporary or permanent block in the atrioventricular junction area. Depending on the degree of block, it can be divided into 3 degrees:

The first degree is prolonged interventricular conduction time, but all atrial impulses can be transmitted to the ventricles;

the second degree is that some impulses cannot reach the ventricles;

In the third degree, all impulses cannot be transmitted to the ventricles, so it is also called complete atrioventricular block, which is an organic heart disease, and temporary atrioventricular block is seen in rheumatic myocarditis, diphtheria and influenza and other acute infections, acute inferior myocardial infarction, etc. Persistent atrioventricular block is seen in coronary heart disease, chronic rheumatic heart disease, Keshan disease, sequelae of myocarditis, and congenital heart disease (such as atrial and ventricular septal defects).

Condition analysis: Hello Tongbian, Intraventricular block, also known as intraventricular block, refers to the conduction block below the bifurcation of the bundle of His. The chamber conduction system consists of three parts:

Right bundle branches, left anterior branches, and left posterior branches, and intraventricular conduction system lesions can affect single, double, or triple branches.

Guidance: According to your account, the medication for this disease**: generally ineffective.

Primary disease**: Patients with acute myocardial ischemia of coronary heart disease should improve the state of myocardial supply disorder as soon as possible, and stop all drug disadvantages that may aggravate conduction block in patients caused by drugs; Comorbidities**: If there is heart failure, it will be treated as heart failure, and if there are other arrhythmias, it will be treated according to the arrhythmia chapter**.

Placement of an artificial pacemaker: permanent pacemaker should be considered in patients with above-bundle branch block and a history of cardiogenic cerebral insufficiency.
