As a result of underlying heart disease, this cardiac conductive tissue can become damaged from ischemia (a deprivation of oxygenated blood). This damage results in the inability of this neural-like tissue to conduct electrical signals and control the heart as efficiently as before, resulting in the cardiac abnormality known as a bundle branch block (BBB).
