Intraatrial block

Intraatrial block is a violation of the conduction of excitation in the atrial myocardium. It manifests itself only as widening and deformation of the P wave on the electrocardiogram.

With intraatrial block, impulses from the sinus node cannot travel normally through the atrial muscle. This leads to a delay in the excitation of part of the myocardium and asynchronous contraction of different parts of the atria.

On the ECG, intraatrial block is manifested by an increase in duration and a change in the shape of the P wave. It becomes widened, double-humped or has a saw-tooth shape. In this case, the PQ interval and the ventricular QRS complex do not change.

Thus, intraatrial block is characterized by a violation of impulse conduction in the atria, which is reflected in changes in the P wave on the ECG while maintaining the normal duration of the PQ and the QRS complex.

Intraatrial block (IAV) is a disturbance in the conduction of excitation in the atria of the heart, which manifests itself only on the electrocardiogram (ECG) in the form of expansion and deformation of the P wave. IAV can be caused by various reasons, such as myocardial infarction, arrhythmia, cardiomyopathy, His bundle block and other heart diseases.

With VVP, the transmission of electrical impulses from the atria to the ventricles of the heart is delayed or blocked. This can lead to heart rhythm disturbances and arrhythmias. However, in most cases, BVP does not cause serious complications and may be asymptomatic.

An ECG is used to diagnose BVP. On the ECG with BVP, you can see the expansion and deformation of the P wave, which reflects the conduction of the impulse from the atria to the ventricles. Changes in other waves, such as the QRS complex and T wave, may also be observed.

Treatment for BVP depends on the cause that caused it. In some cases, treatment of the underlying disease that caused VVP may be necessary. If PVP is caused by an arrhythmia, medications may be prescribed to control the heart rhythm.

In general, VVP is a fairly common atrial conduction disorder. However, if it is asymptomatic, then there is no need for treatment. Regular monitoring by a cardiologist and an ECG will help identify possible problems and prevent the development of complications.
