What is Left Bundle Branch Block?

I recently had a very similar experience, and have insisted on a referral to a cadiologist. It has been a bit of a wake-up call for me, since I exercise regularly, don't smoke, maintain an ideal weight and generally exhibit none of the factors which some suggest accompany Left Bundle Branch Block (LBBB) and which are thought by some to be causal (e.g., high blood pressure, coronary artery disease, etc.).

Basically, LBBB is an abnormality of electrical conduction in the heart that sometimes expresses itself in arthymias.  Sometimes it seems to occur in otherwise healthy individuals, but it is usually a sign of underlying heart disease, which may be serious, and the possibility of this should be thoroughly investigated. Even if not accompanied by other detectible heart problems, seems to increase the risk of out-of-hospital cardiac arrest and sudden death. There is apparently not much by way of treatment of the LBBB itself (other than pacemakers, which are sometimes recommended). At the very least, a little more research on the web will encourage you to seek further medical advice.

Hope this is helpful.

I agree with Anonymous's response. I to am diagnose with it. I am borderline for a pacemaker - which means I don't get one. I am one beta-blocker pills which reduce the change for heart attacks and strokes. I am also on blood pressure and cholestral medication.  My blood pressure and cholestral is under control and I am trying to keep it that way without the meds. I do plan on taking the beta-blockers.  My problem is with energy.  I had lots of energy - now that I have had this for two years, my energy level, breathing has reduced. I trying to find ways to improve my energy. Exercise is getting my strenuous.
