Hi,
Bundle branch block (BBB) is a condition in which there is a delay or obstruction in the transmission of the
heart's electrical impulses.In most people, bundle branch block does not cause any symptoms. In some
people, either left or right bundle branch block may lead to fainting, or to dizziness and the sensation of
being faint. 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, an inflamed or weakened
heart muscle, a viral infection of the heart muscle, high blood pressure, or a heart abnormality that is
present at birth.
It is best that your boyfriend see a cardiologist for further evaluation and make regular appointments to be
sure that the condition does not become worse. There's no specific treatment for many cases of bundle
branch block. It is important to know the underlying cause for proper management. Lifestyle measures such as
cigarette smoking cessation, reduction of the dietary cholesterol and fat, maintaining weight at normal
levels,and exercising regularly may lower the risk of worsening his condition.
Take care and regards.
