heart\u2019s natural pacemaker, down to the atrioventricular (AV) node and then on to the bundle of His, which is a collection of muscle fibers specialized for transmitting electrical impulses.<\/p><p>The bundle of His then divides the signal into left and right branches and sends it on to the ventricles, the heart\u2019s lower chambers, where it tells them when to contract.<\/p><p>If you have bundle branch block, the signals from the bundle of His to either your left or right ventricle are delayed or blocked.<\/p><p>In left<strong> bundle branch block (LBBB)<\/strong> the left-hand electrical pathway is interrupted. The signal still reaches your left ventricle, but it travels there through your right ventricle and gets there slightly late.<\/p><p>This can cause the contraction of your ventricles to be uncoordinated and it can make your heart\u2019s pumping mechanism less efficient.<\/p><p>In some people with LBBB the blockage may be present all the time, but in others it may be intermittent, only happening when exercising or at other times when their heart rate is quite high.<\/p><p>If you want learn more about a normal heartbeat take a look at <strong>Your heart: The basics<\/strong><a
