Bundle Branch Block - BBB

Bundle branch block (BBB) is a pattern that can appear on your electrocardiogram (ECG), which indicates a change in the way the electrical impulses in your heart are being distributed.  BBB may turn out to be just an "incidental finding," or it may turn out to have significant medical indications, depending on its pattern (right or left bundle branch block), its cause, and any underlying heart disease you might have.

So if you have BBB, you will need to work with your doctor to decide what, if anything, needs to be done about it.
