Incomplete bundle branch block sometimes indicates underlying heart disease. But,  when it occurs on the right side (i.e., incomplete RBBB,) it often has no significance at all. So when incomplete bundle branch block is detected it should trigger your Dr. to do a non-invasive search for underlying heart disease (i.e. Echocardiogram, Stress Test). If none is found, then no further tests or treatment is needed.

It is usually an incidental finding in an otherwise asymptomatic person. Are you having any symptoms?

My 4 year old has a complete RBBB and I think they said they weren't sure what caused his most likely his  was from his heart surgery. I googled this little bit. it doesn't really sound like it is a birth defect

Causes

Normally, electrical impulses within your heart's muscle signal it to beat (contract) in a precisely coordinated manner. These impulses travel along a specific pathway, passing from your heart's upper chambers (atria) through a small mass of cells called the atrioventricular (AV) node and then to the lower chambers (ventricles).

As part of this route from the AV node to the ventricles, the impulses move along a slender cluster of cardiac fibers called the "bundle of His" (named after a German physician, Wilhelm His), which divides into two branches — the right and the left bundles — one for each of the heart's ventricles.

If one or both of these branch bundles become injured or damaged — due to a heart attack, for example — this impairment can alter the electrical pathways and interfere with the normal conduction of signals from your heart's upper chambers to the lower chambers. When transmission of these signals is slow or when a complete blockage occurs, the ventricles no longer contract in perfect coordination with one another.

The cause of bundle branch block is often a serious heart condition. Bundle branch block may develop if you have coronary artery disease, and may be the result of:

    * A heart attack (myocardial infarction)
    * An inflamed or weakened heart muscle (cardiomyopathy)
    * A viral infection of the heart muscle (myocarditis)
    * High blood pressure (hypertension)
    * Scar tissue that develops after heart surgery
    * A heart abnormality that is present at birth (congenital), such as atrial septal defect, a hole in the wall separating the upper chambers of the heart

My son had the hole he had one in the upper and lower parts. so they aren't really sure if it was from the holes or the surgery.
good luck and you will most likely have to be followed at first once a year.
