One of the nerves on your heart isn't working as it should do, the one feeding a signal into your left ventricle. They call it a block, but the signal is still activating your left ventricle, causing it to pump but there's a very slight delay. You was probably born with this defect and nothing can be done to correct it unless you have a pacemaker but there would have to be a concerned delay in the left ventricle for this. You are at greater risk of needing a pacemaker at some time with this condition and It's not really dangerous.

There are three fascicles in the heart.  They can be thought of as the electrical system of the heart with each fascicle being a separate cable that transfers electical impulses to various parts of the heart.  A left antarior block implies that one of those fasciles isn't working as well and the other two are filling in for it.  This may be related to a prior heart attack, but more so due to an older age and degenerative disease in the conduction system.  It does not portend a poor prognosis.
