Sometimes rapid breathing occurs due to insufficient conduction of blood and insufficient cellular oxygen supply. Patients face difficulties in breathing air like shortness of breath with slow exertion. Patients may become faint due to low blood pressure. Pain may become severe with time due to improper functioning of the heart. Right ventricular conduction delay shows symptoms that resemble symptoms of other heart diseases. Right ventricular conduction delay symptoms In the case of incomplete right bundle branch block, the QRS interval is between 110 and 120 ms in adults and between 90 and 100 ms in children. In the complete right bundle branch block, the QRS interval is above 120 ms in adults and above 100 ms in children. When we compare complete and incomplete right bundle branch blocks, the duration of QRS varies. Right bundle branch block is considered the most common cause behind right ventricular conduction delay. The QRS interval of the right ventricle is marked positive. When depolarization occurs in the right ventricle, the left one is halfway finished and electrical activity is lost. The bundle branch block may be complete or incomplete.ĭue to the right bundle branch block, the conduction of blood towards the right bundle of His is reduced and slow. In the case of right ventricular conduction delay, the right bundle branch block is responsible. There are three main conditions associated with conduction block which are left bundle branch block, right bundle branch block, and intraventricular conduction delay. A single tissue of any branch of the bundle of His is involved in delayed conduction. It is characterized as a long QRS complex I.e. It may lead to delays in proper management of those heart conditions.Right ventricular conduction delay means late blood pumping from the right ventricle of the heart. A slowed heart rate may lead to fainting, irregular heart rhythms and other serious complications.īecause bundle branch block affects the electrical activity of the heart, it can sometimes complicate the accurate diagnosis of other heart conditions, especially heart attacks. The lack of signaling can slow the heart rate. If both the right and the left bundles are blocked, the main complication is a complete blockage of the electric signaling from the upper to the lower chambers of the heart. Having high blood pressure or heart disease increases the risk of having bundle branch block. Bundle branch block is more common in older adults than in younger people. Risk factors for bundle branch block include: High blood pressure in the pulmonary arteries (pulmonary hypertension).Heart structure problems that are present at birth (congenital heart defects) - such as a hole in the wall separating the upper chambers of the heart (atrial septal defect).Blood clot in the lungs (pulmonary embolism).Thickened, stiffened or weakened heart muscle (cardiomyopathy).Inflammation of the heart muscle (myocarditis).Sometimes, there is no known cause.Ĭauses can include: Left bundle branch block The cause for bundle branch blocks can differ depending on whether the left or the right bundle branch is affected. As a result, the heart beats irregularly. If one or both of these branch bundles are damaged - due to a heart attack, for example - the electrical impulses can become blocked. These impulses travel along a pathway, including two branches called the right and the left bundles. Electrical impulses within the heart muscle cause it to beat (contract).
