A bundle branch block is a delay or obstruction along the pathway that electrical impulses travel in your heart to make it beat. It is not an obstruction of blood flow in an artery or anywhere else. It indicates an âelectricalâ problem.
Usually, left bundle branch block by itself does not cause symptoms. You are more likely to have symptoms if you have other problems in addition to your left bundle branch block. In people with heart failure, left bundle branch block can sometimes make those symptoms worse.
