Thanks for posting your query.
LBBB is caused by the slowing of the electrical signal as it travels down the left bundle branch. Almost any disease process that affects the left ventricular muscle can lead to LBBB.
LBBB usually indicates underlying cardiac pathology. It is seen in dilated cardiomyopathy, hypertrophic cardiomyopathy, hypertension, aortic valve disease, coronary artery disease, and a variety of other cardiac conditions. Occasionally LBBB occurs in apparently healthy people. Your cardiologist must have investigated you properly to rule out the presence of any cardiac pathology before telling it to be insignificant.
Hope this answers your query. I will be glad to answer the follow up queries that you have.
Please accept my answer in case you do not have further queries.
Wishing you good health.
