Third degree atrioventricular block, what to pay attention to in second degree atrioventricular bloc

Third-degree atrioventricular block is an absolute indication for pacemaker fitting.

In third-degree atrioventricular block, all atrial impulses cannot be transmitted to the ventricles.

Symptoms of third-degree atrioventricular block depend on the speed of the ventricular rate and the accompanying symptoms.

Symptoms include tiredness, fatigue, dizziness, syncope, angina, heart failure, etc. If there are concomitant ventricular arrhythmias.

Palpitations may be uncomfortable. If the ventricular rate is too slow.

Cerebral insufficiency may occur.

Temporary loss of consciousness may occur.

Even convulsions. It's called Ass syndrome.

Can be life-threatening.

So. Be sure to have a pacemaker.

The lifespan of a pacemaker is generally five to seven years.

When the battery is depleted, the pacemaker needs to be replaced.

After installation, after debugging, the pacemaker is working normally.

Life is not affected.

Second degree atrioventricular block home remediesAnswerer: Ruan Ying: You must pay attention to the question of second degree atrioventricular block home remedies, and you mentioned that the second degree atrioventricular block home remedies answer for you as follows. The key to having a conduction block is to maintain a certain heart rate and maintain a good cardiac output.

Drugs such as atropine and Xinbao can be used, and you should listen to the opinions of clinicians more on **.

Second-degree atrioventricular block**Answerer: Li JinYou must pay attention to the question of second-degree atrioventricular block**, and you mentioned second-degree atrioventricular block** to answer you as follows. An ECG is different from a Holter ECG in that it only reflects the heart rhythm at a certain point in time, and at other times, it is not necessarily normal.

Therefore, a repeat Holter ECG for conduction block and other arrhythmias is still recommended. If second-degree block persists, the risk needs to be evaluated, and if the risk is high, it is not recommended to continue to participate in long-distance running. **On the basis of the current **, add traditional Chinese medicine decoction.

Respondents with first- to second-degree atrioventricular block: You must pay attention to the problem of first- to second-degree atrioventricular block, and you mentioned that first- to second-degree atrioventricular block will answer you as follows. This diagnostic term is often used during ECG examinations and refers to the ECG pattern that appears when the heart's impulse signal does not pass through the right bundle branch.

Because the right bundle branch is thin and long, and the right bundle branch is supplied only by the right coronary artery, it is susceptible to damage. Right bundle branch block can occur in rheumatic heart disease, mitral stenosis, cor pulmonale, congenital atrial septal defect, coronary heart disease, cardiomyopathy, etc., and may also be caused by unknown causes, even in normal people.

Occasional second-degree atrioventricular block answerer: Hu Gangxue You must pay attention to the problem of occasional second-degree atrioventricular block, and you mentioned that incidental second-degree atrioventricular block answers you as follows. Hello, you have 2nd degree 1st degree atrioventricular block and your heart rate is very slow, already below 30 beats; Although there are no obvious symptoms, a pacemaker** should be considered.

Atrioventricular block is an impulse of the heart that, for some reason, is blocked at the junction of the atria and ventricles in the process of descending.

Depending on the degree of block, atrioventricular block is classified into three degrees: first-degree block, second-degree block, and third-degree block.

First-degree block is the mildest, often asymptomatic, and has no significant effect on cardiac function.

Myocardial inflammation is the most common pathological cause of first-degree block, which can occur in the acute phase of myocarditis or as a sequelae of myocarditis.

For first-degree block, no special treatment is required, such as due to pathological causes such as heart disease, attention should be paid to regular observation of ECG changes.

I also just finished checking, and you have the same atrioventricular transmission to block, check some things, this is the lightest in the transmission to the block, no symptoms, and there is no effect, that is, the p-r interval is greater than 200, if you don't have heart disease such as myocarditis, this is nothing, normal people will also have this kind of first-degree atrioventricular transmission to block symptoms, it may be neurotic, that is, poor rest, mental tension, overwork caused, you had better take care of it, pay attention to rest, After a while, I will check if it has improved, this is also congenital. It's basically not a disease. No need to go out of your way**.

(1) Causes of atrioventricular block can be seen in normal people, and some P-R intervals can be exceeded, and the incidence rate in young and middle-aged people can reach about in normal people over 50 years old. Increased vagus tone is the cause of this and can occur in some athletes. Certain drugs such as digitalis, quinidine, procainamide, potassium salts, receptor blockers, calcium antagonists, and central and peripheral sympathetic blockers such as methyldopa and clonidine can cause p-r interval prolongation.

Many scholars often refer to the prolongation of the P-R interval caused by these factors as AV delay rather than AV block. The prognosis is good. First-degree atrioventricular block is common in rheumatic myocarditis and acute or chronic ischemic heart disease, with an incidence of 4% to 15% in patients with acute myocardial infarction, especially in patients with acute inferior myocardial infarction.

It is also common in myocarditis, hyperthyroidism or adrenal insufficiency, congenital heart disease, cardiac surgery, etc. Most are temporary and can disappear quickly or after a period of time. Primary conduction system fibrosis is the more common cause in older people, presenting with long-term progressive conduction block.

2) Pathogenesis First-degree AV block, also known as AV delay, may be due to conduction delays within the atrium, atrioventricular node, His's bundle, or His-Pur system, or it may be due to a combination of more than one conduction delay. However, in most cases, about 90% occur in the atrioventricular node, a few in the atrium, and a few in the Hippur system, where conduction delays usually do not cause abnormally prolonged p-r intervals, although there are exceptions. Occurs rarely within the bundle of His.

This is due to the labyrinth-like structure of the atrioventricular node favoring the formation of decreasing conduction, while the conduction fibers of the Hiss bundle are arranged in longitudinal rows, which is not conducive to the occurrence of decreasing conduction. First-degree AV block is due to prolonged AV conduction time due to prolonged relative refractory period in the AV junction area, but every atrial activation can be transmitted to the ventricles. 【First-degree atrioventricular block】Other related disease information:
