After a short pause along the bundle of His and legs, the impulses begin their journey towards the ventricles, bringing them into a state of excitation and contraction. This complex system ensures the correct contraction of the main organ sections and hemodynamic processes.
Atrioventricular blockade causes. For its own reason, atrioventricular heart block may lie in violations of Atrioventricular blockade causes. For its own reason, atrioventricular heart block may lie in violations of a functional and organic nature. Functional atrioventricular blockade occurs due to an increase in the tone of the parasympathetic division of the NS. and organic nature. Functional atrioventricular blockade occurs due to an increase in the tone of the parasympathetic division of the NS.
The AV node is a significant part of Acetazolamide pills conduction system, which is responsible for ensuring that the atria and ventricles contract correctly, rhythmically and consistently. The progression of impulses that come from the sinus node slows down a little in the AV node, which allows the atrium to contract and the ventricle to fill with blood.

Atrioventricular block caused by cardiopathology occurs due to fibrosis or sclerosis of the conduction system in a variety of diseases. Rheumatic changes in the myocardium, heart damage in syphilis, ventricular septal infarction, various cardiomyopathies, collagenoses and myocarditis of any genesis (diphtheria, thyrotoxic or autoimmune), amylo-, sarcoidosis, tumor processes in the heart, cardiosclerosis can cause blockade of cardiac genesis. During atrioventricular blockade with an organic defect, at first there can be only a partial blockade, which, with the progression of the underlying disease, can develop into the third degree.
Atrioventricular blockade is many times more often diagnosed in those people who already have a history of any cardiopathology.
Some operations and surgical procedures can also cause the development of AV blockade: installation of a prosthesis on an arterial valve, intervention for congenital heart disease, insertion of a catheter into the right heart, etc. Sometimes doctors also register congenital atrioventricular blockade (about five cases per one hundred thousand newborns). If the child has a blockade from birth, then it can be found that some parts of the conduction system are simply absent. In every fourth such child, atrioventricular blockade is combined with several more anomalies.
