I would not worry too much about the stress test. I perform these for a living, so I've seen more than a few. In all lielyhood, if there is any abnormality on the EKG, then you automatically get a stress test to get clearance. Pilots need to get his kind of clearance too. If you can hump all the gear around on your back and finish in the top third of the class, then I wouldn't be worried. I am weak on arrhythmias like LBBB, but I believe that there is a very high probability that you will be a fireman yet. As far as down the road if this will get worse, I can't even give you an educated guess. I think there is a tendency for LBBB to develop into something else, but htat is really a wild guess. I hope I helped you at least with the stress test.
Good night and good luck.
I can't address the issue of how LBBB will effect your future, but maybe I can put you at ease about the stress test.
My husband is a healthy, fit, 44 year old with LBBB, that was discovered much the same way yours was, on an extensive routine physical exam. He later had an ECG exercise stress test and exercised on the Bruce Protocol for 16 minutes. (Anyone who reaches 12 minutes is said to have an excellent prognosis and only elite athletes get beyond 18.) His assessment stated: "The patient developing exercise induced LBBB should be of no significant consequence in the presence of a normal perfusion scan."
Thank you for the response. Does the fact that it is an LBBB mean that my echo stress test will show a heart condition of some type or is there a good chance that it will come back without any real issues at this time. Meaning that I should just continue to monitor the situation but as long as it doesn't get worse my job performance won't suffer. I don't want to loose everything I have worked for if my heart is really ok. Can this be a normal condition that I just have to keep in shape and take care of my heart or am I basically looking foward to a more serious condition later down the road reguardless of what I do.
thanks once again for the responce.

Bruiserman,
Thanks for the post.
It's hard when we find an abnormality in an otherwise healthy person. Left Bundle Branch block is a marker for underlying structural heart disease. Overall, people with isolated bundle branch block do display a higher prevalence of underlying cardiac pathology and risk. This is why, especially in the setting of your job your physician is concerned.
Overall, I would also probably pursue a stress test to screen you for underlying heart disease. I would also follow you over the long term to ensure all other risk factors such as smoking, lipids and blood pressure was well controlled.
The best thing you can do in the long run is to stay as fit as you are.
good luck
