Right Bundle Branch Block Atypical (Syp.: B. Right Bundle Branch His S-Type, B. Right Bundle Branch His Wilson Type)

Right bundle branch block (R.B.B.B.) is an electrocardiographic disorder characterized by disruption of the conduction of electrical impulses in the right bundle branch, which is responsible for conducting signals along the fibers of the heart. An atypical form of right bundle branch block, also known as R.B.N.H. S-type or B.P.N.G. Wilson type, differs from the classical form of this disorder.

Electrocardiographic manifestations of atypical right bundle branch block include concordance of ventricular complexes in leads I and III. This means that the QRS complexes in the indicated leads have the same polarity - either positive or negative. In addition, there is an expansion of the S wave in leads I, II and III, as well as the presence of a low-amplitude R wave and a positive T wave. These changes in the electrocardiogram are similar to those observed with the classic form of right leg block.

However, atypical right bundle branch block differs from the classic form in terms of the changes observed in the precordial leads. In the chest leads of the electrocardiogram, other characteristic signs may be visible that indicate the atypicality of this form of blockade.

When diagnosing atypical right bundle branch block, it is important to consider the patient's clinical symptoms and history and perform additional tests, such as echocardiography and exercise testing, to rule out other cardiovascular diseases.

Treatment for atypical right bundle branch block may be aimed at eliminating the underlying disease that may cause this conduction disorder. If necessary, patients may be prescribed antiarrhythmic drugs or may require a pacemaker to maintain a normal heart rhythm.

In conclusion, atypical right bundle branch block represents a variant of this electrocardiographic disorder that differs from the classical form. To accurately diagnose and prescribe appropriate treatment, it is necessary to conduct a comprehensive examination of the patient and take into account his clinical picture.

**Right bundle branch block** is a blockade of the passage of electrical impulses along the right bundle branch, causing the ventricles of the heart to contract irregularly.

There are several types of PNPG blockades: - Sinus - Intraventricular - Left bundle branch block - PNPG Atrioventricular conduction

Sinusoidal block: This is a rare variant of RBBB block in which the ventricular rhythm becomes irregular and the interval between ventricular beats becomes
