Some people with bundle branch block don't have any symptoms and don't need treatment.

Some people with bundle branch blocks are born with this condition.

An example is a right bundle branch block.

As calcium concentrations increase, bradyarrhythmias and bundle branch block may develop.

This is known as appropriate T wave discordance with bundle branch block.

A bundle branch block is usually associated with a change in the Electrocardiogram vector.

Another class of electrocardiomyopathies associated with Chagas' disease are the bundle branch blocks.

Bundle branch block can affect the heart's rhythm.

A bundle branch block refers to a defect of the heart's electrical conduction system.

An atrial septal defect is one possible cause of a right bundle branch block.

Bundle branch blocks are usually treated with the surgical insertion of a pacemaker.

The criteria to diagnose a right bundle branch block on the electrocardiogram:

Blocks that occur within the left or right bundle branches are known as bundle branch blocks.

A common finding in the ECG is the presence of incomplete right bundle branch block.

This manifests in a similar fashion to a regular bundle branch block, however is only occurrent under conditions that affect contractile rate.

Electrocardiographic conduction abnormalities: Generally observed on an electrocardiograph as a bundle branch block.

The simultaneous occurrence of left and right bundle branch block leads to total AV block.

In the setting of right bundle branch block, right or left axis deviation may indicate bifascicular block.

Left anterior fascicular block is a cardiac condition, distinguished from left bundle branch block.

This prolongation or delay is an important criterion for diagnosing bundle branch block and ventricular hypertrophy.

Chagasic bundle branch block is presented in chronic Chagas' disease and is considered a moderate electrocardiomyopathy.

People with bundle branch blocks may still be quite active, and may have nothing more remarkable than an abnormal appearance to their ECG.

Tachycardia-dependent bundle branch block can prevent both ventricles from contracting efficiently and can limit the cardiac output of the heart.

A widely split S2 can be associated with several different cardiovascular conditions, including right bundle branch block, pulmonary stenosis and atrial septal defect.

Marked axis deviation, bundle branch block, and AV block are common, as is atrial fibrillation.

This manifests itself as either conduction disturbances (bundle-branch block, atrioventricular block) or cardiomyopathy - often with hypertrophy, restrictive physiology and congestive heart failure.

When left bundle-branch block (LBBB) is accompanied by right axis deviation (RAD), the rare combination is considered to be highly suggestive of dilated or congestive cardiomyopathy.
