Abnormal ECG, heart palpatations

I am 61 year old retired military officer.  Recently an EKG was done by the VA that showed Incomplete right bundle branch block, Left Posterior Fascicular Bloc, and Nonspecific ST abnormality.  I have also been having frequent episodes in which the heart skips a beat, which can last for a couple of hours at a time.  When this happens, I have some minor discomfort in my chest, I get winded, and I am exhausted after the episode is over.  Is this something to be concerned about?  What are possible causes and treatments?  I have been referred to Cardiology, but cannot get an appointment until June 3.

Evidence of an incomplete right bundle branch block and/or left posterior fascicular block may indicate that there is some underlying disease of your heart's conduction system. This can be seen in a number of conditions including older age, like electrical wiring that is getting worn down. However, there are also medical conditions that can cause problems with the conduction system that may warrant further investigation (i.e. heart attack, primary arrhtyhmia, structural heart disease). If there are any symptoms that are occuring, this should be evaluated further by a physician as soon as possible. If the symptoms are so worrisome or continue to persist without relief, this may need to be done more urgently in an ER.
