  • bundle branch block

    I remember being told several years ago that I had a left bundle branch block...don't remember exactly what that is...anyone else have this? (my left ventricle is enlarged)

    BBB - BUndle branch blocks occure on the Left and right side of the heart. I myself have a Left Bundle Branch Block as do many of us with HCM... So what so does this mean???
    as per WEBMD:
    a form of "heart block" HEART BLOCK involving delay or failure of conduction in one of the branches in the bundle of His, as determined by an electrocardiogram. It may be complete or incomplete, transient, permanent, or intermittent, and is also named according to involvement of the left or the right bundle branch. It is impossible to determine if bundle branch block is complete or not. When associated with acute anterior wall myocardial infarction, bundle branch block identifies a high-risk patient
    Shortened.. some of the electrical signals do not get through.
    For those having alcohol septal ablation - and have a RIGHT BBB - you will end up with a pacemaker as the procedure causes you to have a LEFT BBB - therefore you have complete heart block...
    You can live just fine with a Right block OR a Left block - if both are blocked you need a pacer.

    Knowledge is power ... Stay informed!
    YOU can make a difference - all you have to do is try!

      I have a left bundle branch block as a result of my myectomy surgery. I think Lisa's post covers the details well. As with ablation, myectomy surgery can cause LBBB since the obstruction is in the same area as the AV node and the left branch.

        I have had a left bundle branch block myself that was diagnosed in 1986. I am also a member of the November 2002 Cleveland Clinic myectomy team. Hi Bob, hope everything is well.
