bundle branch block

I have some breathing problems. During stress test I was diagnosed with bundle branch block. I have no other symptoms. Dr says that I do not need to be concerned. Do I need to?

Hello...

I am suspecting that your Dr said that you shouldn't because there probably was no evidence of heart disease or defect. Many times a BBB is found incidentaly and of no concern. I have intermittent RBBB  (right bundle branch block) as well as LAFB (left anterior fasicular block) and my Dr told me that it would be fine unless the RBBB progressed from intermittent to permanent. That would leave 1 bundle branch to transmit electrical impulses.

I think that you should believe your Dr and not burden yourself with worry. I am pasting a link to a site that explains, in detail, the physiology of Bundle Branch Blocks. I hope you find it informative:)
